New 1‐phenyl‐ and 1‐(3‐chlorophenyl)piperazines containing a 4‐[3‐(heterocyclic)propyl] fragment were synthesized. It was found that of all the investigated compounds 11b (Ki = 13 ± 2 nM) and 8b (Ki = 38 ± 2 nM) were the most active 5‐HT1A and 5‐HT2A ligands, respectively. Several derivatives (3a, 4a, 8b, 11b, 12b, 13a, and 13b) were selected as good candidates for new, potential antidepressants on
Pyridazino[3,4-b][1,5]benzoxazepin-5(6H)ones substituted with propylene-linked basic side chains were synthesized and investigated for the ability to reverse multidrug resistance (MDR) at vincristine-pretreated HeLa-MDR1 cells. The substances were found to be effective chemosensitizers with activity comparable to that of the known MDR modulator verapamil. The observed antiproliferative effects were

As the matrix metalloproteinases (MMPs) can be massively up-regulated in degenerative tissues and degrade the extracellular matrix, these key enzymes are promising targets for the therapy of cancer and other degenerative diseases. Here, we are presenting a series of new non-peptidic hydroxamate-based matrix metalloproteinase inhibitors, MMPIs, incorporating the iminodiacetic (IDA) hydroxamic acid scaffold, as mimics of truncated peptidic MMPIs. A series of alkylaryl and sulfonylaryl groups, on the IDA basic scaffold, was investigated with the aim of improving potency and selectivity against MMPs involved in degenerative diseases. The sulfonamide based IDA derivatives studied (compounds B1-B3) showed to be potent (nM range) against deep S1' pocket MMPs enzymes (i.e., MMP-2). (c) 2006 Elsevier Ltd. All rights reserved.

A series of 4-amino-3(2H)-pyridazinones substituted at position 2 with arylpiperazinylalkyl groups and analogues were synthesized and their antinociceptive effect was evaluated in the mouse abdominal constriction model. Preliminary SARs studies were performed. Several of the novel compounds dosed at 100 mg/kg s.c. significantly reduced the number of writhes induced by the noxious stimulus. Compound 12e showed 100% inhibition of writhes and was able to protect all the treated animals from the effect of the chemical stimulus. Subsequent dose-response studies revealed 12e to be almost 40-fold more potent than the structurally related Emorfazone.
