β-Analogs of PLG (l-prolyl-l-leucyl-glycinamide): Ex-chiral pool syntheses and dopamine D2 receptor modulating effects
摘要:
Starting from (S)- and (R)-aspartic acid enantiomerically pure P-proline derivatives were synthesized. These chiral building blocks were transformed into P-analogs of the dopamine receptor modulating peptide PLG. According to dopamine receptor binding studies, significant enhancement of [H-3]pramipexole binding was observed for the isomeres 1a,b and 2a-c. The derivative Ib revealed an activity comparable to PLG. (C) 1998 Elsevier Science Ltd. Air rights reserved.
lead discovery of DL0805, a new ROCK I inhibitor, showing potent inhibitory activity (IC50 6.7 μM). Herein, we present the lead optimization of compound DL0805, resulting in the discovery of 24- and 39-fold more-active analogues 4a (IC50 0.27 μM) and 4b (IC50 0.17 μM), among other active analogues. Moreover, ex-vivo studies demonstrated that 4a and 4b exhibited comparable vasorelaxant activity to the
in covalent targeted inhibitors in drug discoveryagainst previously “undruggable” sites and targets. These molecules typically feature an electrophilic warhead that reacts with nucleophilic groups of protein residues, most notably the thiol group of cysteines. One main challenge in the field is to develop versatile utilizable warheads. Here, we characterize the unique features of novel arsenous warheads
