- HIV protease inhibitors
-
The present invention discloses novel isoquinoline carboxamide derivatives which are HIV protease inhibitors or prodrugs thereof, a process for their manufacture, pharmaceutical compositions and the use of such compounds in medicine. In particular, the compounds are hydroxyethylamine tripeptide mimetics which act as inhibitors of the HIV aspartyl protease, an essential enzyme in the replicative life cycle of HIV. Consequently, the compounds of this invention may be advantageously used in the treatment of HIV infection, either alone or in combination with other inhibitors of HIV viral replication or with pharmacoenhancers such as cytochrome P450 inhibitors.

- An Infrared Study of Rotational Isomerism in Thiazole-2-carboxylates
-
A series of alkyl thiazole-2-carboxylates containing a range of substituents at the 4- and 5-positions has been prepared.Solutions of these esters (mostly new compounds) show well resolved doublets in the i.r.C=O region which arise from rotational isomers.The higher wavenumber components are assigned to the more polar carbonyl O,S-anti-s-trans-rotamers and the lower wavenumber components to the carbonyl O,S-syn-s-trans-forms.Small, but systematic, differences between the methyl esters are noted.
