摘要:
Drugs for potentiating the effect of cancer therapy based on the function mechanism of injuring DNA which contain compounds represented by the general formula (I) or physiologically acceptable salts thereof as the active ingredient: (I) wherein R represents aryl-substituted alkyl, heteroaryl-substituted alkyl, cycloalkyl-substituted alkyl or cyclic hydrocarbyl (wherein the cyclic hydrocarbyl may be saturated, partly saturated or aromatic); and Z represents hydrogen or C1-6 alkyl, provided that Z may be bonded to R to form a cyclic structure. These drugs potentiate the effect of cancer therapy and lessen the administration dose of anticancer agents and/or radiation dose, thereby relieving side effects accompanying cancer therapy.
摘要:
The present invention relates to a novel class of sulfonamides which are aspartyl protease inhibitors. In one embodiment, this invention relates to a novel class of HIV aspartyl protease inhibitors characterized by specific structural and physicochemical features. This invention also relates to pharmaceutical compositions comprising these compounds. The compounds and pharmaceutical compositions of this invention are particularly well suited for inhibiting HIV-1 and HIV-2 protease activity and consequently may be advantageously used as anti-viral agents against the HIV-1 and HIV-2 viruses. This invention also relates to methods for inhibiting the activity of HIV aspartyl protease using the compounds of this invention and methods for screening compounds for anti-HIV activity.
(i) matrix metalloproteinase (MMP) inhibitors containing sulfonylamino acid derivatives of the formula (Ia): wherein R 1 is hydrogen, C1-4 alkyl; R 2 is hydrogen, C1-8 alkyl etc.; E is -CONR 3 -, in which R 3 is hydrogen, C1-4 alkyl etc., -NR 3 CO-, -CO-O-, -O-CO- etc.; A is hydrogen, C1-8 alkyl, C3-7 cycloalkyl, or Ar; J is bond, C2-4 alkylene etc.; G is -(CH 2 ) m -, in which m is 2, 3 or 4, or in which R 6 and R 7 is hydrogen, C1-8 alkyl etc.; and non-toxic salts thereof, (ii) novel sulfonylamino acid derivatives of the formula (Ib): wherein all the symbols are as defined for formula (Ia), with the exclusion of certain compounds; and non-toxic salts thereof, and (iii) processes for the preparation of the compounds of formula (Ib).
The compounds of formulae (Ia) and (Ib) are useful for prevention and/or treatment of diseases induced by overexpression or excess activity of MMP, such as rheumatoid diseases, arthrosteitis, unusual bone resorption, osteoporosis, periodontitis, interstitial nephritis, arteriosclerosis, pulmonary emphysema, cirrhosis, cornea injury, metastasis, invasion or growth of tumor cells, autoimmune diseases (Crohn's disease, Sjogren's syndrome etc.), diseases caused by vascular emigration or infiltration of leukocytes, or arterialization.
摘要:
A 2,3-diaminopropionic acid derivative represented by general formula (1) or a pharmaceutically acceptable salt thereof. This compound is useful as a platelet aggregation inhibitor, cancer metastasis inhibitor, wound remedy or bone resorption inhibitor.
摘要:
A heat-sensitive recording material includes a heat-sensitive recording layer containing a basic dye and a developer and provided on a supporting body, in which the developer is at least one type of an N-substituted amino acid derivative represented by the following General Formula: (R-X) m -Y-(Z) m ... (1) (In Formula (1), R represents an alkyl group or an aryl group which may have a substituent. X is a group bonded to the N-terminus of Y, and represents -OCO-, -SO 2 NHCO-, -NHCO-, -NHCS-, or -SO 2 -. Y represents an amino acid residue or a peptide residue. Z represents a group bonded to the C-terminus of Y and represents an OH group or an OR" group. When Y is an amino acid residue other than a cystine residue or when Y is a peptide residue not having a cystine residue, m = 1, and when Y is a peptide residue having n cystine residues, m = n + 1 and n is 1 or 2.)
