Definitions
- the present invention describes pharmaceutical compositions containing the 1,112-pyrazolaminocycline hydrochloride compound (HPMCCI) - a minocycline derivative (HMCCI) - and pharmaceutically acceptable excipients, and their use for relieving neuropathic pain.
- HPMCCI-containing composition may be used alone or in combination with other drugs to treat patients with neuropathic pain.
- the compound HPMCCI has no antimicrobial effect, which, compared to minocycline, can reduce adverse reactions, allowing greater adherence of patients to treatment.
- Tetracyclines were discovered in the late 1940s and are a family of natural drugs derived from the metabolites of different Streptomyces sp. (chlortetracycline, oxytetracycline) as well as semi-synthetic drugs (metacycline, doxycycline, HMCCI, limecycline, rolitetracycline and tigecycline). Chlortetracycline and oxytetracycline are drugs obtained from Streptomyces aureofaciens and Streptomyces rimosus, respectively.
- tetracyclines were later discovered, including Streptomyces aureofaciens tetracycline, Streptomyces rimosus and Streptomyces viridofaciens and Streptomyces demethylchloretracycline. aureofaciens.
- the most recently discovered member of this pharmacological class was tigecycline, a third generation tetracycline derived from HMCCI that has been approved in the United States of America for the treatment of patients with severe skin and intra-abdominal infections (CHOPRA, I .; ROBERTS , M. Tetracycline antibiotics: mode of action, applications, molecular biology, and epidemiology of bacterial resistance (Microbiol Mol Biol Rev, v. 65, no. 2, pp. 232-60, 2001).
- Tetracyclines inhibit bacterial protein synthesis by preventing coupling of the transporter aminoacyl RNA to the ribosomal receptor site. They are drugs that induce a predominantly bacteriostatic effect, showing activity against several Gram-positive and Gram-positive bacteria. negative and also against chlamydia, mycoplasma, rickettsia and protozoa. In addition, some tetracycline derivatives are potent antifungal agents. Doxycycline has been included in the model list of essential drugs proposed by the World Health Organization (WHO, 2010) not only in the class of antibacterial drugs, but also in the class of drugs used for malaria prophylaxis and treatment of patients with this parasitic disease.

- the use of HPMCCI in the treatment of neuropathic pain is associated with several advantages, since the few drugs available to treat patients with diseases of this nature are not very effective, associated with the fact that HPMCCI is potentially safer than HMCCI as it is devoid of antimicrobial activity.

- Example 2 Evaluation of the interaction of HMCCI and HPMCCI compounds with calcium (11) The ability of the HMCCI and HPMCCI compounds to interact with calcium (11) was assessed by spectrophotometric titration involving 3 ml of an aqueous solution of the compound at pH 7. 2 (maintained by the TRIS buffer solution) with aliquots of calcium chloride solution (ll). The system was kept at 25 ° C. Figures 3 and 4 show the electronic spectra obtained during the experiment.
- the first antibacterial activity tests were performed quantitatively by the serial macrodilution method. Antibacterial activity tests were performed following NCCLS standards (2002, 2003). Staphylococus aureus (ATCC ® 6538) and Pseudomonas aeruginosa (ATCC ® 27853) strains were inoculated into Mueller Hinton broth, both incubated at 37 ° C for 18 to 24 h (PERNAK, J. et al. Synthesis and antimicrobial activities of new pyridinium and benzimidazolum chlorides Eur J Med Chem, v. 36, no. 4, pp. 313-20, 2001).
- the reference for inoculum turbidity was measured by analyzing its absorption spectrum in the visible region at wavelengths 530 nm and 625 nm and should provide an absorbance value between 0.08 and 0.1, so that the The inoculum concentration is 10 8 colony forming units (CFU). 100 ⁇ _ were taken from the inoculum and transferred to another tube containing 9.9 ml_ Mueller Hinton broth, so that the inoculum concentration in this tube was 10 6 CFU.
- HMCCI was used as a positive control in tests designed to evaluate the activity of its derivative against S. aureus and P. aeruginosa. After 20 h incubation at 37 ° C, the minimum inhibitory concentrations (MIC) of the compounds were determined.
- Table 2 MIC values found for HMCCI against S. aureus ATCC '6538 and P. aeruginosa ATCC® 9027
- the MIC values are in accordance with the range of values presented for this compound against quality control strains.
- the increase in HPMCCI MIC values, when compared with those of the starting tetracycline, may be attributed to the pyrazole ring formation with the presence of carbon-bound nitrogen C 1 1 and C12, which led to the loss of antibacterial activity (SAIKALI, Z .; SINGH, G. Doxycycline and other tetracyclines in the treatment of bone metastasis (Anticancer Drugs, v. 14, no. 10, pp. 773-8, 2003).
- a second battery of tests was performed using ninety clinical samples: 30 Staphylococcus aureus, 30 Staphylococcus spp. negative coagulase and 30 of Escherichia coli.
- the strains were sensitive to a wide range of antibacterial drugs, as demonstrated in a test conducted according to the method proposed by the Clinical Laboratories Standards Institute (CLSI, 2011).
- MIC minimal inhibitory concentrations of minocycline and HPMCCI were assessed by the agar dilution method (CLSI, 201 1). Drug stock solutions were added to Muller-Hinton agar (BD Difco TM, USA) leading to final concentrations of 0.125 to 64 pg / mL. Bacterial inocula were prepared by direct suspension of the colony in saline to obtain a density equivalent to the 0.5 McFarland standard (approximately 1 x 10 8 colony-forming units / mL) and then inoculated onto the Muller-Hinton agar with the drugs using a replicator. Steers (Steers, Foltz et al., 1959).
- Staphylococcus aureus (ATCC® 25923) reference strains Staphylococcus epidermidis (ATCC® 12228) and Escherichia coli (ATCC® 25922) were included as a control.
- the MIC was considered the lowest concentration sufficient to inhibit bacterial growth following CLSI standards (201 1).
- HMCCI 2 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
- HMCCI 9 4 0 0 0 0 0 0 0 0 0 0 0 0 0 0
- the bacteria tested are considered sensitive to HMCCI when their growth inhibited at a concentration of 16 pg / mL or less, CLSI 201 1.
- Example 4 Evaluation of HPMCCI Antifungal Activity Eleven Candida albicans strains were included in this study. All samples were kept on Sabouraud dextrose agar at 4 ° C. Prior to testing, samples were transferred to a new tube containing Sabouraud dextrose agar at 37 ° C for 24 h. Fungi suspensions were prepared in saline (0.85% sodium chloride, m / v) and the transmittance was adjusted to 85% at 530 nm on a spectrophotometer.
- the resulting suspension (1 to 5 X 10 6 colony forming units / mL) was vortexed for 15 h and cell density was adjusted to 1 to 5 X 0 3 colony forming units / mL in RPMI-1640 medium (Inlab, Brazil).
- the microdilution assay was conducted using sterile RPMI-1640 medium buffered with morpholinopropanesulfonic acid (0.155 mol / L, Sigma-Aldrich, USA) as the test medium.
- the solutions containing each of the drugs tested were dissolved in distilled and sterile water. Then, serial dilution in RPMI-1640 was performed, finally obtaining a concentration range of 128 to 0.25 pg / mL.
- Results were expressed in ng / mL, and MIC was visually defined as the lowest concentration capable of inhibiting fungal growth when compared to the control group.
- MIC was capable of inhibiting 80% of fungal growth (NCCLS, 2002).
- Surgical nerve constriction procedures are based on the technique described by Bennett and Xie, 1988 (BENNETT, GJ; XIE, YK. Peripheral mononeuropathy in rat that produces disorders of pain sensation like those seen in man. Pain, v. 33, n 1, pp. 87-107, 1988).
- Figure 4 shows the threshold curves for right paw withdrawal as a function of time after intraperitoneal (i.p.) administration of the HPMCCI compound or its vehicle in rats undergoing sciatic nerve constriction surgery or false surgery.
- Example 6 Antinociceptive effect of HPMCCI administered per os.
- HPMCCI administered per os is of great importance in a therapeutic context, as oral administration is the most convenient for drug administration.
- Figure 6 shows data on the antiallodynamic effect of per os administered HPMCCI, which can be achieved by increasing the intraperitoneally administered effective dose by 5-fold (from 50 to 250 mg / kg).
- Surgery was performed as previously described in Example 5, and the drug was administered by gavage, in a volume of 2 mL / kg, in saline containing 5% sucrose m / v (Labsynth ® , Diadema, Brazil).
