Abstract
Three distinct chemical classes for the control of gastrointestinal nematodes are available: benzimidazoles, imidazothiazoles, and macrocyclic lactones. The relentless development of drug resistance has severely limited the usefulness of such drugs and the search for a new class of compounds preferably with a different mode of action is an important endeavor. Marcfortine A (1), a metabolite of Penicillium roqueforti, is structurally related to paraherquamide A (2), originally isolated from Penicillium paraherquei. Chemically the two compounds differ only in one ring; in marcfortine A, ring G is six-membered and carries no substituents, while in paraherquamide A, ring G is five-membered with methyl and hydroxyl substituents at C14. Paraherquamide A (2) is superior to marcfortine A as a nematocide. 2-Desoxoparaherquamide A (PNU-141962, 53) has excellent nematocidal activity, a superior safely profile, and is the first semi-synthetic member of this totally new class of nematocides that is a legitimate candidate for development. This review describes the chemistry, efficacy and mode of action of PNU-141962.

Abstract
The imidazoquinoline (R)-5,6-Dihydro-N,N-dimethyl-4H-imidazo[4,5,1-ij]quinolin-5-amine [(R)-3] is a potent dopamine agonist when tested in animals but surprisingly shows very low affinity in in vitro binding assays. When incubated with mouse or monkey liver S9 microsomes, (R)-3 is metabolized by N-demethylation and oxidation to (R)-5,6-dihydro-5-(methylamino)-4H-imidazo[4,5,1-ij]quinolin-2(1H) -one [(R)-6], intermediate metabolites, where N-demethylation to the imidazoquinoline (R)-4 and where oxidation to the imidazoquinolinone (R)-5 has taken place, are also observed in these incubates. A cross-species study on the metabolism of (R)-3 in vitro has shown large variations in the extent of metabolism from species to species. Imidazoquinolinones (R)-5 and (R)-6 have comparable activity to (R)-3 in animals and also show good dopaminergic (D2) and serotonergic (5HT1A) activities in binding assays. It is probable that these metabolites account at least in part for the in vivo activity found for (R)-3. Efficient syntheses for compounds 3-6 as single enantiomers from quinoline are presented together with information on the biological activities and metabolic stabilities of these compounds.

Abstract
A previously reported renin inhibitor, Boc-Pro-Phe-N(Me)His-Leu psi [CHOHCH2]Val-Ile-Amp (U-71038), was altered by the incorporation of polar, hydrophilic moieties at either end, e.g., tris(hydroxymethyl)aminomethane (THAM) or glucosamine urea groups at the N-terminus, and the THAM amide or aminomethylpyridine N-oxide at the C-terminus. These modified analogues, with dramatically improved water solubility, all retained the potent renin inhibitory activity of U-71038 in vitro. The fact that good activity was maintained in these new analogues, which possess hydrophilicity and steric bulk considerably different from the parent compound, suggests that neither end of these molecules is critical for recognition and binding of the inhibitors by renin. These modified analogues were evaluated in a rat model, and several exhibited hypotensive activity after both oral and iv administration which was greater in magnitude and longer in duration than that caused by equimolar doses of U-71038. Furthermore, unlike U-71038, the oral activity of these analogues was not dependent upon administration in a citric acid vehicle.
