- Synthesis and crystal structures of 2,3,12,13-tetraalkoxy-21,23- dithiaporphyrins and 2,3-dialkoxy-21-monothiaporphyrins
-
The tetraalkoxy and dialkoxy substituted 21,23-dithiaporphyrins and 21-monothiaporphyrins, respectively, having methoxy, butoxy, octyloxy and dodecyloxy substituents at β-thiophene carbons were synthesized and characterized. The X-ray structure was solved for tetrabutoxy substituted 21,23-dithiaporphyrin and it exhibited a more planar structure compared with unsubstituted S2TPP, whereas the dimethoxy substituted 21-monothiaporphyrin showed a saddle shaped structure similar to unsubstituted STPPH. A series of 21,23-dithia and 21-monothiaporphyrins having methoxy, butoxy, octyloxy and dodecyloxy substituents at β-thiophene carbons were synthesized and characterized.

- Esters of Thiodiglycollic and Thiodipropionic Acids and 2,5-Dicarboxy-3,4-dihydroxythiophene as Potential Slow Acting Anticancer Agents
-
A series of esters of thiodiglycollic and thiodipropionic acids and 2,5-dicarboxy-3,4-dihydroxythiophene have been synthesised with a view to testing their anticancer properties.The esters, as against parent acids are expected to have a prolonged effect.
