    • 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 formulawherein A is oxygen or sulfur coupled to the right by a single or double bond; R2 is selected from the group consisting of hydrogen, aryl, lower aliphatic substituents, particularly alkyl and lower alkyl ester; R4-R7 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 alpha, beta, unsaturated ketones; R8-R11 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; R12 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.
