Abstract: Novel antitumor epipodophyllotoxin glucoside lactam derivatives are prepared by first converting the lactone ring of the parent compound to the open-chain trans-hydroxy hydrazide, condensing the hydrazide with a carbonyl compound to form the corresponding hydrazone, and finally cyclizing the trans-hydroxy hydrazone using diethylazodicarboxylate and triphenylphosphine.

Abstract: The invention relates to chemically stable, concentrated solutions of cis-diamminedinitratoplatinum which are pH-stabilized with nitric acid and are readily convertible to parenteral cisplatin solutions by addition of sources of chloride ion.

Abstract: Novel 4'-esters, 4'-carbonates and 4'-carbamates of 4'-demethylepipodophyllotoxin glucosides are disclosed. These agents exhibit antitumor activity in animals.

Abstract: Disclosed herein are isoxazole-4-carboxamides having the formula ##STR1## wherein R.sup.1 is C.sub.3-6 cycloalkyl and R.sup.2 is selected from the group consisting of C.sub.1-5 alkyl, C.sub.2-5 alkenyl, C.sub.2-5 alkynyl, C.sub.3-6 cycloalkyl, phenyl, and phenyl substituted with at least one group selected from C.sub.1-5 alkyl, C.sub.1-5 alkoxy, C.sub.1-5 alkylthio, and halo-substituted C.sub.1-5 alkyl; with the proviso that when R.sup.1 is cyclopropyl, R.sup.2 is not methyl, ethyl, or cyclobutyl; or R.sup.1 is C.sub.1-5 alkyl and R.sup.2 is phenylmethyl wherein the ring portion is opt. substituted with a halo-substituted C.sub.1-5 alkyl group. These compounds have antiinflammatory and antiarthritic activities and are also useful as intermediates in the preparation of .beta.-ketonitriles.
