Abstract: Analogs of substance P and eledoisin which are conformationally constrained by the presence of a lactam in the peptide chain demonstrate greater selectivity and increased protease stability and are useful as analgesic, anti-inflammatory, antihypertensive, central nervous system agents, and stimulants of lachrymal secretion. The compounds are prepared by standard peptide synthetic procedures.
Abstract: Prodrugs of 3-hydroxy-3-methylglutarylcoenzyme A (HMG-CoA) reductase inhibitors which are useful as antihypercholesterolemic agents and are represented by the following general structural formula (I): ##STR1## the amido ester moiety of which is in the L-configuration, and pharmaceutically acceptable salts thereof are disclosed.

Abstract: A group of 4-substituted-5-nitroimidazoles is described, having effective antiprotozoal activity with much less mutagenicity than is shown by known 5-nitroimidazoles.
Abstract: Benzenesulfonamides with a substituted-alkyl-S(O).sub.n -substituent are carbonic anhydrase inhibitors useful in the treatment of elevated intraocular pressure.
Abstract: There are disclosed novel formulations of avermectin compounds and a substrate which demonstrate markedly enhanced insecticidal activity over that which would be observed with other formulations. Avermectin natural product compounds and certain semisynthetic derivatives thereof are compounds known to be highly effective broad-spectrum antiparasitic and pesticidal agents. However, when such compounds are formulated into the instant composition, the activity observed is increased to at least 10-times that which would be expected. The instant substrate is preferably a highly dispersed, amorphous form of hydrophyllic silicon dioxide.
Abstract: Certain novel cyclic ureas are disclosed herein as dermal penetration enhancers of drug absorption. Also disclosed herein are compositions, methods of treatment and processes for preparing said cyclic urea compounds.
Abstract: Aromatic sulfonamides with a saturated heterocycle fused thereto are carbonic anhydrase inhibitors useful in the treatment of elevated intraocular pressure.
