Abstract: There is provided novel aryloxyanilides and related compounds of the formula ##STR1## wherein R.sup.1 is --OR, --CO.sub.2 R, or halogen with R being C.sub.1-4 alkyl;R.sup.2 is R, cyclopropyl, C.sub.2-4 alkenyl or --CH.sub.2 OR; andX is O, S, CH.sub.2, NR, SO, SO.sub.2 or COwhich are melatonergic agents and are useful in the treatment of circadian rhythm-related disorders and other conditions affected by melatonin activity.
Abstract: Compounds of the formula ##STR1## wherein R.sup.1 and R.sup.4 each are independently hydrogen, halogen, C.sub.1-4 alkyl, C.sub.1-4 alkoxy, or trifluoromethyl;R.sup.2, R.sup.3, R.sup.5 and R.sup.6 each are independently hydrogen, halogen C.sub.1-4 alkyl or C.sub.1-4 alkoxy;tet is ##STR2## n is an integer of from 0 to 2, inclusive; A is ##STR3## R.sup.7 is hydrogen, C.sub.1-4 alkyl, C.sub.1-4 alkoxy(lower) alkyl or (2-methoxyethoxy)methyl;X is --OH or .dbd.O; andR.sup.8 is hydrogen, a hydrolyzable ester group or a cation to form a non-toxic pharmaceutically acceptable salt,are novel antihypercholesterolemic agents which inhibit cholesterol biosynthesis. Intermediates and processes for their preparation are disclosed.
Abstract: A novel antibiotic complex designated herein as BBM-1675 complex is produced by fermentation of certain novel strains of Actinomadura verrucosospora. The complex may be separated into two major components, BBM-1675 A.sub.1 and A.sub.2, and four minor components, BBM-1675 A.sub.3, A.sub.4, B.sub.1 and B.sub.2, and such components exhibit both antimicrobial activity and antitumor activity.
Abstract: This invention provides novel cephalosporin intermediates, 7.beta.-amino-3-[(Z)-1-propen-1-y1]-3-cephem-4-carboxylic acid and esters thereof having the general formula ##STR1## wherein the configuration of the 3-propenyl group is Z sometimes referred to as cis- and R is hydrogen or a conventional carboxy-protected group, or a physiologically hydrolyzable esterifying group, and acid addition salts thereof and the metal salts of the foregoing substance wherein R is hydrogen. These compounds are useful as intermediates for preparation of orally active cephalosporins.
Abstract: Novel compounds of the formula ##STR1## wherein each R.sup.1 is the same and is a straight or branched chain alkynyl group containing from 3 to 9 carbon atoms, inclusive, which are useful intermediates in the preparation of anti-ulcer agents, are prepared by reacting cystamine (VI) with an N-cyano-N'-alkynyl-S-methylisothiourea of the formula ##STR2## in which R.sup.1 is as defined above.
