Isoxazoles

Abstract

A compound selected from the group consisting of a compound of the formula ##STR1## wherein R.sub.1 is hydrogen or alkyl of 1 to 3 carbon atoms; R.sub.2 is cycloalkyl of 3 to 6 carbon atoms; R.sub.4 is selected from the group consisting of halogen, nitrile, nitro, --SCH.sub.3, -alkylcarbonyl of 1 to 6 carbon atoms, cycloalkylcarbonyl of 3 to 6 carbon atoms, --CX.sub.3, --WCX.sub.3, --(CH.sub.2).sub.n CX.sub.3, --(CX.sub.2).sub.n CX.sub.3, --W(CX.sub.2).sub.n CX.sub.3 and a --W(CH.sub.2).sub.n CX.sub.3, in which X is halogen, W is oxygen or sulfur, and n is 1, 2 or 3; and R.sub.5 is selected from the group consisting of hydrogen, alkyl of 1 to 3 carbon atoms and cycloalkyl of 3 to 6 carbon atoms; with the proviso that if R.sub.5 is hydrogen, R.sub.4 is not --SCH.sub.3 or --CF.sub.3 and their non-toxic pharmaceutically acceptable salts having anti-prolifera-tive, anti-inflammatory and anti-tumor activity.
