Abstract: The present invention relates to certain substituted caprolactam compounds of formula (I), where R1 is (C1-6)alkyl or (C3-6)cycloalkyl; R2 hydrogen or (C1-6)alkyl; X is (C1-12)alkynylene; (C2-12)alkynylene; m is 0 or 1; and R3 is (C3-8)cycloalkyl; or an aromatic ring system selected from (II, III, IV and V), where R4 is hydrogen, chloro, or methoxy; R5 is hydrogen, chloro, (C1-18)alkyl or (C1-18)alkoxy, and Z is oxygen, sulfur, N—H, or N—CH3; or a pharmaceutically acceptable acid addition salt thereof, where possible, pharmaceutical compositions containing said compounds, the use of said compounds in treating tumors and to a process for making said compounds.

Abstract: A pharmaceutical composition that inhibits or slows the growth of viruses in animals, particularly in mammals, is disclosed. This same composition is can be used to treat viral infections, particularly HIV. The composition comprises from about 10 mg to about 10000 mg of a carbamic acid ester derivative of the formula: wherein X is independently oxygen or sulfur, R is selected from the group consisting of hydrogen and alkyl having from 1 to 4 carbon atoms, R1 is selected from the group consisting of hydrogen and alkyl having from 1 to 4 carbon atoms, wherein R2 is independently selected from the group consisting of hydrogen and alkyl having from 1 to 4 carbon atoms, and wherein Y is selected from the group consisting of hydrogen, chloro, fluoro, bromo, hydroxy, oxychloro and sulfhydryl or pharmaceutical addition salt or prodrug thereof. The most preferred compound is (4-chlorophenyl)-carbamic acid, 3-(hexahydro-3-ethyl-1-methyl-2-oxo-1H-azepin-3-yl) 2 phenyl ester.
