Synthesis and activity of novel homodimers of Morita-Baylis-Hillman adducts against Leishmania donovani: A twin drug approach.

It is reported here the synthesis of novel Homodimers 12-19 of Morita-Baylis-Hillman adducts (MBHA) from one-pot Morita-Baylis-Hillman Reaction (MBHR) between aromatic aldehydes as eletrophiles and ethylene glycol diacrylate as Michael acceptor (35-94% yields) using cheap and green conditions. The bioactivities were evaluated against promastigote form of Leishmania donovani. All homodimers showed to be more potent than corresponding monomers.
