Acetylenic linkers in lead compounds: a study of the stability of the propargyl-linked antifolates.

Propargyl-linked antifolates that target dihydrofolate reductase are potent inhibitors of several species of pathogenic bacteria and fungi. This novel class of antifolates possesses a relatively uncommon acetylenic linker designed to span a narrow passage in the enzyme active site and join two larger functional domains. Because the use of alkyne functionality in drug molecules is limited, it wa...

Acetylenic inhibitors of sheep vesicular gland oxygenase.

Biosynthesis of prostaglandins could be stopped by several acetylenic acids. They interfered with the oxygenase activity of the sheep vesicular gland enzymic system in two distinct patterns: an instantaneous, concentration-dependent effect and a time-dependent, destructive effect. Constants for both effects are reported. No measurable oxygen consumption tias observed with the acetylenic analogs...
