Marine-derived compounds have been explored and considered as possible antitumor agents. In this study, we analyzed extracts of the sponge Cribrochalina vasculum for their ability to inhibit tumor cell proliferation. Screening identified two acetylenic compounds of similar structure that showed strong tumor-specific toxicity in non-small cell lung carcinoma (NSCLC) cells and small-cell lung car...

Mouse brain glutamate decarboxylase(s) was specifically titrated in vivo and in crude brain homogenates by a combination of gabaculine and [a-'H]acetylenic yaminobutyric acid. This specific titration is based on the differential spectra of action of these two mechanism-based enzyme inactivators. The specificity of the titration in vitro was demonstrated by showing that the time course of radioa...

the synthesis of twenty five esters of testosterone (17β -hydroxyandrost- 4-en-3-one) is described. all esters are derivatives of cycloalkycarboxylic acids. some of the esters possess α- , β -and/or & - substitution in the ester side-chain. the work was undertaken in order to evaluate long-acting male antifertility effect of such esters. most of the compounds, especially compound no.1, were fou...
