METHODS AND COMPOSITIONS
FOR
STIMULATING NEURITE GROWTH The following statement is a full description of this invention, including the best method of performing it known to us: -la- METHODS AND COMPOSITIONS FOR STIMULATING NEURITE GROWTH TECHNICAL FIELD OF THE INVENTION The present invention relates to methods and pharmaceutical compositions for stimulating the growth of neurites in nerve cells. The compositions comprise a neurotrophic amount of a compound which binds to the FK- 506 binding protein (FKBP) and a neurotrophic factor, such as nerve growth factor NGF. The methods comprise treating nerve cells with the above-described compositions or compositions comprising the FKBP binding compound without a neurotrophic factor. The methods of this invention can be used to promote repair of neuronal damage caused by disease or physical trauma.
15 BACKGROUND OF THE INVENTION Immunophilins are a family of soluble proteins that mediate the actions of immunosuppressant drugs such as cyclosporin A, FK506 and rapamycin. Of particular interest is the 12 kDa immunophilin, FK-506 binding 20 protein (FKBP12). FKBP12 binds 14-506 and rapamycin, leading to an inhibition of T-cell activation and proliferation. Interestingly, the mechanism of action of FK-506 and rapamycin are different. For review, see, S.
H. Solomon et al., Nature Med., 1, pp. 32-37 (1995).
FK-506 binds to FKBP12 and the resulting complex binds to and inhibits calcineurin, a cytoplasmic phosphatase. The phosphatase activity of calcineurin is necessary for dephosphorylation and subsequent translocation into the nucleus of the transcription factor NF-AT. NF-AT causes interleukin-2 gene activation which in turn mediates T-cell proliferation.
The rapamycin-FKBP12 complex, on the other -2hand, associates with a protein of unknown function, termed RAFT1/FRAP. This tripartite complex is known to inhibit various kinases in the cell p70S6, p34cdc2, cdk2) which are necessary for cell cycle progression in T-cells. Rapamycin is also known to be a potent antagonist of FK-506, presumably by acting as a competitive inhibitor for the FKBP12 binding.
More recently, it has been discovered that FKBP plays other important roles in the body. It has been found that FKBP12 forms a complex with the intracellular calcium ion channels the ryanodine receptor (RyR) and the inositol 1,4,5-triphosphate receptor (IP 3 R) [T.
Jayaraman et al., J. Biol. Chem., 267, pp. 9474-77 (1992); A. M. Cameron et al., Proc. Natl. Acad. Sci. USA, S 15 92, pp. 1784-44 (1995)], helping to stabilize calcium release. The ryanodine receptor has been found in skeletal muscle, cardiac muscle, brain and other excitable tissues. IP 3 R mediates intracellular calcium release elicited by hormones and neurotransmitters that act at the cell surface to activate phospholipase C and generate inositol 1,4,5-triphophase
(IP
3 Most IP 3 R is found associated with the endoplasmic reticulum, but some may occur on the cell surface and mediate calcium flux into the cell.
25 For both the RyR and the IP 3 R, it has been demonstrated that FK506 and rapamycin are capable of dissociating FKBP12 from the receptor. In each case, the "stripping" off of FKBP12 leads to increased leakiness of the calcium channel and lower intracellular calcium concentrations.
Another role of FKBP12 is the regulation of neurite outgrowth in nerve cells. W. E. Lyons et al.
[Proc. Natl. Acad. Sci. USA, 91, pp. 3191-95 (1994)] demonstrated that FK506 acts synergistically with nerve growth factor (NGF) in stimulating neurite outgrowth in a -3rat pheochromocytoma cell line. Interestingly, rapamycin did not inhibit the effects of FK-506 on neurite outgrowth, but rather was neurotrophic itself, displaying an additive effect with FK-506. In sensory ganglia, FK- 506 demonstrated similar neurotrophic effects, but those effects were blocked by rapamycin. These results led the authors to speculate that FK-506 was exerting its neurotrophic effect through its complexing with FKBP12 and calcineurin and inhibition of the latter's phosphatase activity. Alternatively, the authors proposed FK-506 was acting via a "stripping" mechanism, such as that involved in the removal of FKBP12 from RyR and IP 3
R.
*In view of the wide variety of disorders that S 15 may be treated by stimulating neurite outgrowth and the relatively few FKBP12-binding compounds that are known to S.:possess this property, there remains a great need for additional neurotrophic, FKBPl2-binding compounds.
SUMMARY OF THE INVENTION 20 Applicant has solved the problem referred to above by discovering that two genera of novel FKBP12binding compounds he had previously co-invented also possess neurotrophic activity. Applicant had previously described a series of acylated amino acid derivatives which bind to FKBP12 in PCT patent publications WO 92/19593 and WO 94/07858. Another series of FKBP12 ligands are described in applicant's United States Patents 5,192,773 and 5,330,993 and PCT patent publication WO 92/00278. Each series of compounds stimulate neurite outgrowth in the presence of exogenous or endogenous NGF.
The compositions provided comprise a compound from one of the two genera described above and a neuronal -4growth factor. The methods described herein employ those previously described compounds and compositions comprising them to effectuate neurite outgrowth are useful to treat nerve damage caused by various diseases and physical traumas.

The neurotrophic activity of the FKBP12 binding compounds of this invention is directly related to their affinity for FKBP12 and their ability to inhibit FKBP12 rotomase activity. In order to quantitate these properties, several assays known in the art may be employed. For example, competitive LH20 binding assays using labelled FK-506 as a reporting ligand have been described by M. W. Harding et al., Nature, 341, pp. 758- (1989) and by J. J. Siekierka et al., Nature, 341, pp.
755-57 (1989).
Preferably, the assay measures inhibition of FKBP12 rotomase activity. Such an assay has also been described by M. W. Harding et al., supra and by J. J.
Siekierka et al., supra. In this assay the isomerization of an artificial substrate N-succinyl-Ala-Ala-Pro-Phep-nitroanilide is followed spectrophotometrically.
The assay includes the cis form of the substrate, FKBP12, the inhibitor and chymotrypsin. Chymotrypsin is able to cleave p-nitroanilide from the trans form of the substrate, but not the cis form. Release of p- 15 nitroanilide is measured.
The second component in each of the pharmaceutical compositions described above is a neurotrophic factor. The term "neurotrophic factor", as used herein, refers to compounds which are capable of stimulating growth or proliferation of nervous tissue.
As used in this application, the term "neurotrophic factor" excludes the FKBP12 binding compounds described herein, as well as FK-506 and rapamycin.
Numerous neurotrophic factors have been 25 identified in the art and any of those factors may be utilized in the compositions of this invention.

The amount of both FKPB12 binding compound and the neurotrophic factor that may be combined with the 15 carrier materials to produce a single dosage form will vary depending upon the host treated, the particular mode of administration. The two active ingredients of the pharmaceutical compositions of this invention act synergistically to stimulate neurite outgrowth.
20 Therefore, the amount of neurotrophic factor in such compositions will be less than that required in a monotherapy utilizing only that factor. Preferably, the compositions should be formulated so that a dosage of between 0.01 100 mg/kg body weight/day of the FKBP12 binding protein can be administered and a dosage of between 0.01 100 ug/kg body weight/day of the neurotrophic can be administered to a patient receiving these compositions.
It should also be understood that a specific dosage and treatment regimen for any particular patient will depend upon a variety of factors, including the activity of the specific compound employed, the age, body weight, general health, sex, diet, time of administration, rate of excretion, drug combination, and the judgment of the treating physician and the severity of the particular disease being treated. The amount of active ingredients will also depend upon the particular FKBP12 binding compound and neurotrophic factor in the composition.
According to another embodiment, this invention provides methods for stimulating neurite outgrowth. Such methods comprise the step of treating nerve cells with any of the FKBP12 binding compounds described above.
Preferably, this method is used to stimulate neurite outgrowth in a patient and the FKBP12 binding compound is formulated into a composition additionally comprising a pharmaceutically acceptable carrier. The amount of FKBP12 binding compound utilized in these methods is between about 0.01 and 100 mg/kg body weight/day.
15 According to an alternate embodiment, the method of stimulating neurite outgrowth comprises the additional step of treating nerve cells with a neurotrophic factor, such as those contained in the pharmaceutical compositions of this invention. This embodiment includes administering the FKBP12 binding compound and the neurotrophic agent in a single dosage form or in separate, multiple dosage forms. If separate dosage forms are utilized, they may be administered concurrently, consecutively or within less than about 25 hours of one another.
Preferably, the methods of this invention is Sused to stimulate neurite outgrowth in a patient.
The methods and compositions of this invention may be used to treat nerve damage caused by a wide variety of diseases or physical traumas. These include, but are not limited to, Alzheimer's disease, Parkinson's disease, ALS, stroke and ischemia associated with stroke, neural paropathy, other neural degenerative diseases, motor neuron diseases, sciatic crush, spinal cord injuries and facial nerve crush.
-21- In order that the invention described herein may be more fully understood, the following examples are set forth. It should be understood that these examples are for illustrative purposes only and are not to be construed as limiting this invention in any manner.
EXAMPLE 1 FKBP12 Binding Assay The inhibition of FKBP rotomase activity by the preferred FKBP12 binding compounds present in the compositions of this invention was assayed. In this assay various quantities of FKBP12 binding compound (0.1 nM 10 M) were added to cis-N-succinyl-Ala-Ala-Pro-Phep-nitroanilide in the presence of FKBP12 and chymotrypsin. FKBP12 converts the cis form of the 15 substrate to the trans form. This allows chymotrypsin to cleave p-nitroanilide from the substrate. Release of pnitroanilide was measured spectrophotometrically. This assay allowed me to measure the change in the first order rate constant of the rotomase activity as a function of 20 FKBP12 binding compound concentration and yielded an estimate of apparent K i The most preferred FKBP12 binding compounds utilized in the compositions and methods of this invention and their calculated K i are tabulated below.

lylmethoxy)phenyl Assay Of Neurite Outgrowth- in Pci 9 Culture-s In order to directly determine the neurotrophic -31activity of the FKBP12 binding compounds utilized in this invention, the assay described by W. E. Lyons et al., Proc. Natl. Acad. Sci. USA, 91, pp. 3191-95 (1994) is carried out.
PC12 rat pheochromocytoma cells are maintained at 37°C and 5% CO 2 in Dulbecco's modified Eagle's medium (DMEM) supplemented with 10% heat-inactivated horse serum (HS) and 5% heat-inactivated fetal bovine serum (FBS).
The cells are then plated at 105 per 35mm culture well coated with 5 pg/cm 2 rat tail collagen and allowed to attach. The medium is then replaced with DMEM 2% HS and 1% FBS, NGF (1-100 ng/ml) and varying concentrations of an FKBP12 binding compound (0.1 nM 10 pM). Control cultures are administered NGF without FKBP12 binding 15 compound.
The FKBP12 binding compounds utilized in this invention cause a significant increase in neurite outgrowth over control cultures.
~EXAMPTLE 3 20 Assay of Neurite Outgrowth in Dorsal Root Ganalion Culture Another way to directly determine the neurotrophic activity of the FKBP12 binding compounds utilized in this invention is the dorsal root ganglion 25 culture assay also described by W. E. Lyons et al., Proc.
Natl. Acad. Sci. USA, 91, pp. 3191-95 (1994).
In this assay, dorsal root ganglia are dissected from 16 day rat embryos and cultured in collagen-coated 35mm dishes with N2 medium at 37 0 C in a 15% CO 2 environment. Sensory ganglia are then treated with various concentrations of NGF (0 100 ng/ml) and an FKB12 binding compound (0.1 nM 10 pM). Ganglia are observed every two days under a phase contrast microscope and axon lengths are measured. Control cultures either -32lack FKBP12 binding compound or lack FKBP12 binding compound and NGF.
The FKBP12 binding compounds utilized in this invention cause a significant increase in neurite outgrowth over control cultures which lack such compounds in both the presence and absence of NGF.
While I have hereinbefore presented a number of embodiments of this invention, it is apparent that my basic construction can be altered to provide other embodiments which utilize the methods of this invention.
Therefore, it will be appreciated that the scope of this invention is to be defined by the claims appended hereto rather than the specific embodiments which have been presented hereinbefore by way of example.
*a* o METHOD 1 The neurotrophic activity of eight compounds of the present invention was determined using a PC12 culture assay.
Neurotrophic activity is reported in terms of the concentration of test compound that causes an increase in neurite outgrowth over control cultures lacking such compound.
PC12 rat pheochromocytoma cells were maintained at 37( C and 5% C02 in Dulbecco's modified Eagle's medium (DMEM) supplemented with 10% heat-inactivated horse serum, heat-inactivated fetal bovine serum, 2 mM glutamine, 1 mM sodium pyruvate and Penn/Strep. For differentiation in the presence of nerve growth factor, cells were plated at 2 X 4 cells per 1.88 cm? culture well coated with rat tail collagen at 5 ug/cm2 and allowed to attach. 24 hours later, medium was replaced with DMEM supplemented with 1% horse serum, 2 mM glutamine, 1 mM sodium pyruvate, Penn/Strep, S mouse NGF (suboptimal concentration) and DMSO or compound.
Each condition was performed in triplicate. Each triplicate was on a distinct culture plate. All compounds were added and scored in a blinded manner. Neurons bearing processes longer than IX the cell body were scored as positive.
METHOD 2 Another assay, which utilizes ventral mesencephalic cultures, was used to assess neurotrophic activity.
The ventral mesencephalic region was dissected out of embryonic day 15 Sprague-Dawley rat embryos (Harlan), dissociated into single cell suspension by a combination of trypsinization and trituration (Costantini et al., Neurobiol Dis. 1998; 5;97-106). Dissociated VM cells were plated into poly-L-ornithine-coated 96-well plates at a density of 85,000 cells/well in 100 uL of DMEM supplemented with 18% heat-inactivated horse serum, 0.24% glucose, 2 mM glutamine and 50 u/ml pernicillin/streptomycin and incubated in a C02 incubator. After one day in culture (DIV1), the medium was replaced with 100 uL of a defined medium (DMEM supplemented with Ix N2 cocktail (Gibco-BRL), 0.12% glucose, 2 mM glutamine, and 50 units/ml penicillin/streptomycin) containing DMSO or various concentrations of the neurophilin compounds. On DIV5, neuroexcitotoxic injury was induced by the addition of various concentrations of the glutamate receptor agonist NMDA (100-400 uM). Cultures were incubated with the neurotoxin for 20 hours and the effects of neurophilin compounds were assessed using high affinity 3H-dopamine uptake according to a procedure published by Park and Mytilineou (Brain Res 1992; 599:83-97).
The results of the above two assays are shown below in Table 3 and Table 4.
