Novel compounds of the formula (I), a process for their preparation and their use as collagenase inhibitors are described:
in which,R1 is hydrogen, alkyl, or optionally substituted aryl; R2 is hydrogen, or acyl such as
where Z is optionally substituted aryl; R3 is C3-6 alkyl; R4 is hydrogen, alkyl, -CH2-R10 where R10 is optionally substituted phenyl or heteroaryl, or a group
where R11 is hydrogen, alkyl, or -CH2-Ph where Ph is optionally substituted phenyl, and R12 is hydrogen or alkyl; and Rs is hydrogen, alkyl, or a group
where R13 is hydrogen, or alkyl, and R14 is hydroxy, alkoxy, or -NR6R7, where each of R6 and R7 is hydrogen or alkyl, or R6 and R7 together with the nitrogen atom to which they are bonded form a 5-, 6- or 7-membered ring with an optional oxygen or sulphur atom in the ring or an optional further nitrogen atom optionally substituted by alkyl.
本发明描述了式 (I) 的新型化合物、其制备方法及其作为胶原酶抑制剂的用途:
其中,R1 是氢、烷基或任选取代的芳基;R2 是氢或酰基,如
其中 Z 是任选取代的芳基; R3 是 C3-6 烷基; R4 是氢、烷基、-CH2-R10(其中 R10 是任选取代的苯基或杂芳基)或一个基团
其中 R11 是氢、烷基或-CH2-Ph(其中 Ph 是任选取代的苯基),R12 是氢或烷基;以及 Rs 是氢、烷基或一个基团
其中 R13 是氢、或烷基,R14 是羟基、烷氧基或-NR6R7,其中 R6 和 R7 各自是氢或烷基,或 R6 和 R7 与它们所键合的氮原子一起形成 5、6 或 7 元环,环中任选有一个氧原子或硫原子,或任选有另一个氮原子任选被烷基取代。
