Synthesis and biological evaluation of benzimidazole derivatives as potent AMP-activated protein kinase activators
摘要:
Design, synthesis and structure-activity relationships of beU:/AP/DTD501/BMC/4818nzimidazole derivatives as activators of the AMP-activated protein kinase (AMPK) are presented in this paper. AMPK is the central component of a protein kinase cascade that plays a key role in the regulation of energy balance. Once activated, AMPK initiates a series of responses that are aimed at restoring the energy balance of the cell and recent studies have indicated that AMPK plays an important role in regulation of the whole-body energy metabolism. The following study based on the lead compound S27847 involved modification of three regions of this compound. Preliminary structure activity relationships are being described. (c) 2006 Elsevier Ltd.

Benzoxazoles or benzimidazoles can be rapidly and efficiently synthesized from a variety of carboxylic acids with 2-aminophenols or 1,2-phenylenediamines in one simple step, respectively. The use of commercially available PS-PPh3 resin combined with microwave heating delivered a variety of benzoxazoles and benzimidazoles in high yields and purities.

Semicarbazide as an effective transientdirectinggroup for C(sp3)−Harylation of 2‐methylbenzaldehydes is described. Various substituted 2‐benzylbenzaldehydes are efficiently synthesized by this strategy. The salient features of this protocol are the use of inexpensive transientdirectinggroup, wide scope of substrates with good functional group compatibility, up to 98% yield, and applicability to
