Artemisinin-polypyrrole conjugates: synthesis, DNA binding studies and preliminary antiproliferative evaluation.

abstract：:Loperamide (1a), an opioid receptor agonist, is in clinical use as an antidiarrheal agent. Carbon/silicon exchange (sila-substitution) at the 4-position of the piperidine ring of 1a (R3 COH→R3 SiOH) leads to sila-loperamide (1b). Sila-loperamide was synthesized in a multistep procedure, starting from triethoxyvinylsil...
