Description

Amide compound, composition containing same and application thereof

Technical Field

The invention belongs to the technical field of medicines, and particularly relates to an amide compound, a composition containing the amide compound and application of the amide compound.

Background

Protein tyrosine kinases play an important role in cellular regulation and have been observed to be aberrantly expressed or mutated in cancer cells or autoimmune diseases. Protein tyrosine kinases are enzymes that catalyze the transport of phosphate groups from ATP to tyrosines located on protein substrates. Many growth factor receptor proteins function as tyrosine kinases to transmit cellular signals. The interaction between growth factors and their receptors generally controls cell growth, but aberrant signal transduction resulting from mutation or overexpression of any one of the receptors often induces a variety of cancers or autoimmune diseases (e.g., rheumatoid arthritis).

EGFR tyrosine kinase inhibitors (EGFR-TKIs) are molecular targeted drugs against EGFR, which block further transmission of signals into cells, inhibit tumor cell growth and induce apoptosis thereof, mainly by competitively binding with ATP to the binding site of the catalytic domain of EGFR tyrosine kinase located on the cell surface. Currently, EGFR-TKI such as erlotinib and gefitinib are widely used in clinic. Although EGFR inhibitors such as gefitinib and erlotinib have remarkable curative effect on EGFR mutant advanced non-small cell lung cancer (NSCLC), it is subsequently found that EGFR-TKI has primary or secondary resistance when used for treating NSCLC, and that AZD9291 (Osimetinib, Axitinib) can be orally taken for treating EGFR second mutation of lung cancer patients. AZD9291 is an oral, irreversible, third-generation EGFR inhibitor (EGFR-TKI) with improved therapeutic efficacy in NSCLC patients with EGFR-TKI resistance and T790M mutation. However, patients taking AZD9291 still develop symptoms of acquired resistance. The mechanism of acquired resistance mutation of AZD9291 comprises: EGFR C797S mutation, FGFR1 amplification, HER2 amplification, C-Met amplification or MAPK alternative pathway activation, histological transformation (partial transformation to small cell lung cancer), or multiple other gene mutations. (reference: Oxnard et al Nature Medicine,2015,21,560-

AZD9291 forms a covalent bond with cysteine C797 at the ATP binding site, and the C797S mutation affects the binding of the covalent bond, similar to the resistance mechanism of the BTK inhibitor Ibrutinib (Ibrutinib). A heavy article is published in Nature 2.2016, a new generation of targeting drug EAI045 capable of overcoming AZD9291 drug resistance is recorded, and for C797S mutation, EAI045 and erbitux are jointly applied to a mouse model, so that the effective rate is as high as 80%. (reference: M.J.Eck et. Nature,2016,534,129-132)

Therefore, treating advanced NSCLC faces new challenges, and we need to develop new exploration and search for new strategies.

Administration of drugs

The pharmaceutical compositions provided by the present invention may be administered by a number of routes including, but not limited to: oral, parenteral, inhalation, topical, rectal, nasal, buccal, vaginal, by implant or other modes of administration. For example, parenteral administration as used herein includes subcutaneous administration, intradermal administration, intravenous administration, intramuscular administration, intraarticular administration, intraarterial administration, intrasynovial administration, intrasternal administration, intracerebrospinal administration, intralesional administration, and intracranial injection or infusion techniques.

Typically, an effective amount of a compound provided herein is administered. The amount of compound actually administered can be determined by a physician, as the case may be, including the condition to be treated, the chosen route of administration, the compound actually administered, the age, weight, and response of the individual patient, the severity of the patient's symptoms, and the like.

When used to prevent a condition according to the invention, a subject at risk of developing the condition is administered a compound provided herein, typically based on physician's advice and under the supervision of a physician, at a dosage level as described above. Subjects at risk of developing a particular disorder, typically include subjects with a family history of the disorder, or those determined to be particularly susceptible to developing the disorder by genetic testing or screening.

The pharmaceutical compositions provided herein may also be administered chronically ("chronic administration"). By long-term administration is meant administration of the compound or pharmaceutical composition thereof over a long period of time, e.g., 3 months, 6 months, 1 year, 2 years, 3 years, 5 years, etc., or may continue for an indefinite period of time, e.g., for the remainder of the subject's life. In some embodiments, chronic administration is intended to provide a constant level of the compound in the blood over a prolonged period of time, e.g., within the therapeutic window.

Various methods of administration may be used to further deliver the pharmaceutical compositions of the present invention. For example, in some embodiments, the pharmaceutical composition may be administered as a bolus, e.g., in order to rapidly increase the concentration of the compound in the blood to an effective level. The bolus dose depends on the targeted systemic level of the active ingredient, e.g., an intramuscular or subcutaneous bolus dose results in a slow release of the active ingredient, while a bolus delivered directly to the vein (e.g., by IV intravenous drip) can be delivered more rapidly, allowing the concentration of the active ingredient in the blood to rise rapidly to an effective level. In other embodiments, the pharmaceutical composition may be administered as a continuous infusion, e.g., by IV intravenous drip, to provide a steady state concentration of the active ingredient in the body of the subject. Furthermore, in other embodiments, a bolus dose of the pharmaceutical composition may be administered first, followed by continuous infusion.

Oral compositions may take the form of bulk liquid solutions or suspensions or bulk powders. More generally, however, the compositions are provided in unit dosage form for convenient administration of the precise dosage. The term "unit dosage form" refers to physically discrete units suitable as unitary dosages for human patients and other mammals, each unit containing a predetermined quantity of active material suitable for the purpose of producing the desired therapeutic effect, in association with a suitable pharmaceutical excipient. Typical unit dosage forms include prefilled, pre-measured ampoules or syringes of liquid compositions, or in the case of solid compositions, pills, tablets, capsules and the like. In such compositions, the compound is typically a minor component (about 0.1 to about 50% by weight, or preferably about 1 to about 40% by weight), with the remainder being various carriers or excipients and processing aids useful in forming the desired form of administration.

For oral dosages, a representative regimen is one to five oral dosages, particularly two to four oral dosages, typically three oral dosages per day.

In order to provide a blood level similar to, or lower than, the use of the injected dose, a transdermal dose is generally selected in an amount of from about 0.01 to about 20% by weight, preferably from about 0.1 to about 10% by weight, and more preferably from about 0.5 to about 15% by weight.

From about 1 to about 120 hours, especially 24 to 96 hours, the injection dosage level is in the range of about 0.1 mg/kg/hour to at least 10 mg/kg/hour. To obtain sufficient steady state levels, a preload bolus of about 0.1mg/kg to about 10mg/kg or more may also be administered. For human patients of 40 to 80kg, the maximum total dose cannot exceed about 2 g/day.

Liquid forms suitable for oral administration may include suitable aqueous or nonaqueous carriers, as well as buffers, suspending and dispersing agents, coloring and flavoring agents, and the like. Solid forms may include, for example, any of the following components, or compounds with similar properties: a binder, for example, microcrystalline cellulose, gum tragacanth or gelatin; excipients, for example, starch or lactose, disintegrants, for example, alginic acid, Primogel or corn starch; lubricants, for example, magnesium stearate; glidants, e.g., colloidal silicon dioxide; sweetening agents, for example, sucrose or saccharin; or a flavoring agent, for example, peppermint, methyl salicylate, or orange flavoring.

Injectable compositions are typically based on sterile saline or phosphate buffered saline for injection, or other injectable excipients known in the art. As previously mentioned, in such compositions, the active compound is typically a minor component, often about 0.05 to 10% by weight, with the remainder being injectable excipients and the like.

Transdermal compositions are typically formulated as topical ointments or creams containing the active ingredient. When formulated as an ointment, the active ingredient is typically combined with a paraffinic or water-miscible ointment base. Alternatively, the active ingredient may be formulated as a cream with a cream base, for example of the oil-in-water type. Such transdermal formulations are well known in the art and typically include other components for enhancing stable skin penetration of the active ingredient or formulation. All such known transdermal formulations and compositions are included within the scope of the present invention.

The compounds of the present invention may also be administered by transdermal means. Thus, transdermal administration can be achieved using a reservoir (reservoir) or porous membrane type, or a patch of various solid matrices.
