摘要:
Anthraquinone compounds of the general formula (I) or a salt thereof (Formula I) in which R1 to R4 are each selected from the group consisting of H, C1-4 alkyl, X1, -NHR0N (R5)2 in which R0 is a C1-12 alkanediyl and each R5 is H or optionally substituted C1-4 alkyl, and a group of formula (II) in which at least one of R6,R7 and R8 is selected from X2 , and X2 substituted C1-4 alkyl and any others are H or C1-4 alkyl; R9 is selected from H, C1-4 alkyl, X2 and X2 substituted C1-4 alkyl; m is 0 or 1; n is 1 or 2; X1 is a halogen atom, a hydroxyl group, a C1-6 alkoxyl group, an aryloxy group or an acyloxy group; and X2 is a halogen atom, a hydroxyl group, a C1-6 alkoxyl group, an aryloxy group or an acyloxy group; provided that at least one of R1 to R4 is a group of formula (II). The N-oxides are useful prodrugs which are selectively bioreduced in hypoxic tumours to the corresponding cyclic amine derivatives. The amine compounds are cytotoxic and may be used as alkylating agents having topoisomerase II inhibiting activities in cancer therapy.

The invention is also directed to a method for cyclizing N-[(aliphatic or aromatic)carbonyl]-2-aminoacetamide compound to a cyclic compound selected from the group consisting of a 1,4-benzodiazepine-2,5-dione derivative, diketopiperazine derivative, ketopiperazine derivative, lactam derivative, 1,4-benzodiazapine derivative and dihydroquinoxalinones derivative, and the cyclized compound.
摘要:
The present invention relates to compounds that inhibit a5b1 function, processes for their preparation, pharmaceutical compositions containing them as the active ingredient, to their use as medicaments and to their use in the manufacture of medicaments for use in the treatment in warm blooded animals such as humans of diseases that have a significant angiogenesis or vascular component such as for treatment of solid tumours. The present invention also relates to compounds that inhibit a5b1, and also that exhibit appropriate selectivity profile(s) against other integrins.
