Published: June 1998

A new class of potent, orally active phenyl piperazine-based GH secretagogues have been discovered from attempts to mimic the arrangement of the phenyl substituent in the spiroindanyl piperidine and spiroindoline sulfonamide privileged structures of 4 and 1, respectively. The best of these compounds, 18 (EC50 = 2.8 nM) is nearly as potent as MK-0677 for releasing GH from rat pituitary cells.

The facile and efficient protocol for the synthesis of N-phenyl piperazine based di-thio-carbamates has been reported under neat conditions. A library of novel piperazine based di-thio-carbamates (3a-h) in excellent yields has been prepared. Solvent free, catalyst free and easy work up conditions make this protocol an attractive synthetic protocol to achieve novel biologically active di-thio-carbamates.

In the present study, anti-leishmanial evaluation of twenty four structurally diverse compounds based on benzopiperidine, benzopyridine and phenylpiperazine nucleuses against Leishmania infantum has been reported. Cytotoxicity studies of all the compounds were performed on murine non-infected splenocytes. Tested compounds exhibited weak to potent activity against promastigote (IC 3.

We recently identified a series of mitotically acting piperazine-based compounds that potently increase the sensitivity of colon cancer cells to apoptotic ligands. Here we describe a structure-activity relationship study on this compound class and identify a highly active derivative ((4-(3-chlorophenyl)piperazin-1-yl)(2-ethoxyphenyl)methanone), referred to as AK301, the activity of which is governed by the positioning of functional groups on the phenyl and benzoyl rings. AK301 induced mitotic arrest in HT29 human colon cancer cells with an ED50 of ≈115 nm.

Aggrecanases, particularly aggrecanase-1 (ADAMTS-4) and aggrecanase-2 (ADAMTS-5), are believed to be key enzymes involved in the articular cartilage breakdown that leads to osteoarthritis. Thus, aggrecanases are considered to be viable drug targets for the treatment of this debilitating disease. A series of (1S,2R,3R)-2,3-dimethyl-2-phenyl-1-sulfamidocyclopropanecarboxylates was discovered to be potent, highly selective, and orally bioavailable aggrecanase inhibitors.

Objectives: 'Party pills' have found use worldwide as a substitute for amphetamine-derived designer drugs. Whilst some information exists about the metabolism of these drugs, there is little information about their ability to inhibit the metabolism of co-administered drugs. This study aimed to determine whether predictions can be made about global interactions between 'party pills' constituents and other drugs metabolised by the same cytochrome P450 (CYP) isoenzymes.
