Cardiac tissue engineering might be useful in treatment of diseased myocardium or cardiac malformations. The creation of functional, biocompatible contractile tissues, however, remains challenging. We hypothesized that coupling of arginine-glycine-as

An optically active, alkynyl analogue of norleucine (Nle), L-2-amino-4-hexynoic acid (Aha), was substituted for Met in the solution synthesis of the Boc-protected C-terminal heptapeptide analogue of substance P. Treatment of the resulting alkynyl pep

New dithiane or dithiolane derivatives of gossypol and gossypolone were synthesized with dithiolethane or dithiolpropane in the presence of BF(3)/Et(2)O. These thioderivatives exhibited low toxicity on KB cells (human epidermoid carcinoma cells of th
The Bronchorelaxant Effect of Helicidine, a Helix Pomatia Extract, Involves Prostaglandin E2 Release

Pharmaceutical Biology. 36:13-19
Helicidine is a biological extract prepared from the snail Helix pomatia L. and used in man as an anti-tussive agent. However , its mechanisms of action are not fully defined. In this study, we have investigated a possible relaxant effect of helicidi
Use of BOP-Cl in the presence of Boc-amino monothioacids for the thioacylation of iminoacid residues

Bioorganic & Medicinal Chemistry. 4:2201-2209
BOP-Cl was found to be an efficient coupling reagent for the introduction of thiopeptide bonds on imino acid residues (Pro, Sar). Boc-amino monothioacids were coupled at moderate temperature (0 degree C-RT) with fair yields and with retained optical

Dynorphin A-(1 – 13)-Tyr-Leu-Phe-Asn-Gly-Pro (Dyn Ia) was previously shown to be a highly potent and selective κ opioid peptide. Four analogs of Dyn Ia are synthesized by the solid-phase procedure, introducing pseudo CH2NH linkage between position

New analogues of the N-terminal fragment of substance P [Arg-Pro-Lys-Pro, SP(1–4)] were synthesized and their activities on histamine release from rat peritoneal mast cells were compared. The potency of these compounds decreases in the following or

A series of pseudopeptides, analogues of neurokinin selective agonists, in which a peptide bond was replaced by a (CH2NH) bond were synthesized. The biological activities of these compounds were determined on selective pharmacological preparations: t

Optical Schiff’s bases of gossypol were prepared with chiral gossypol and ethylamine. As has been similarly observed among the gossypol enantiomers, the (–)-gossypol ethylimine was more active than either the (+)-gossypol ethylimine or the racemi
