Methinylogation Approach in Chiral Pharmacophore Design: from Alkynyl‐ to Allenyl‐carbinol Warheads against Tumor Cells
Abstract Extension of a structure–activity relationship study of the antitumor cytotoxicity of lipidic dialkynylcarbinols (DACs) is envisaged by formal methinylogation of one of the ethyndiyl moieties of the DAC warhead into the corresponding allenylalkynylcarbinol (AllAC) counterpart.
