A new class of cyclin dependent kinase inhibitors that also have antiproliferative activity in human tumor cell line assays are described. Most of these compounds satisfy the formula
1
wherein A is oxygen or sulfur coupled to the right by a single or double bond; R
2
is selected from the group consisting of hydrogen, aryl, lower aliphatic substituents, particularly alkyl and lower alkyl ester; R
4
-R
7
are independently selected from the group consisting of alkoxy, amino, acyl, aliphatic substituents, particularly alkyl, alkenyl and alkinyl substituents, aliphatic alcohols, particularly alkyl alcohols, aliphatic nitriles, particularly alkyl nitriles, cyano, nitro, carboxyl, halogen, hydrogen, hydroxyl, imino, and &agr;, &bgr;, unsaturated ketones; R
8
-R
11
are independently selected from the group consisting of aliphatic substituents, particularly alkyl, alkenyl and alkinyl substituents, particularly lower aliphatic substituents, alipahatic alcohols, particularly alkyl alcohols, alkoxy, acyl, cyano, nitro, epoxy, haloalkyl groups, halogen, hydrogen and hydroxyl; R
12
is selected from the group consisting of aliphatic groups, particularly lower alkyl groups, aliphatic alcohols, particularly alkyl alcohols, carboxylic acids and hydrogen. Compositions comprising effective amounts of such compounds also are described. These compounds and compositions can be used in a method for inhibiting the proliferation of living cells in a subject comprising administering an effective amount of the compound(s), or composition(s) comprising the compound(s), to a subject to inhibit the proliferation of living cells, such as neoplastic cells.
描述了一类新型的细胞周期依赖性激酶抑制剂,这些抑制剂在人类肿瘤细胞系实验中还具有抗增殖活性。其中大多数化合物符合以下公式:其中A是氧或硫,通过单键或双键与右侧连接;R2选择自氢、芳基、较低的脂肪基取代物,特别是烷基和较低的烷基酯;R4-R7独立地选择自烷氧基、氨基、酰基、脂肪基取代物,特别是烷基、烯基和炔基取代物、脂肪醇,特别是烷基醇、脂肪腈,特别是烷基腈、氰基、硝基、羧基、卤素、氢、羟基、亚甲基、β-甲基、不饱和酮;R8-R11独立地选择自脂肪基取代物,特别是烷基、烯基和炔基取代物,特别是较低的脂肪基取代物、脂肪醇,特别是烷基醇、烷氧基、酰基、氰基、硝基、环氧基、卤代烷基、卤素、氢和羟基;R12选择自脂肪基,特别是较低烷基,脂肪醇,特别是烷基醇,羧酸和氢。还描述了包含这些化合物有效量的组合物。这些化合物和组合物可用于抑制体内细胞增殖的方法,包括向受体内施用化合物的有效量或含有该化合物的组合物的有效量,以抑制细胞增殖,如肿瘤细胞。
