Design, synthesis and insulin-sensitising effects of novel PTP1B inhibitors
摘要:
Fifteen novel sulfathiazole-related compounds were designed as PTP1B inhibitors based on a previously reported allosteric inhibitor (1) of PTP1B. These compounds were synthesized and evaluated against human recombinant PTP1B. Six compounds (3, 4, 8 and 14-16) exhibited significant inhibitory activity against PTP1B. The most active compound (16) showed IC50 value of 3.2 mu M and kinetic analysis indicated that it is a non-competitive inhibitor of PTP1B. Furthermore, compound 16 demonstrated excellent selectivity to PTP1B over other PTPs. It also displayed in vivo insulin sensitizing effect in the insulin resistant mice. (C) 2013 Elsevier Ltd.

Cystobactamid 861-2 is the most active member of these antibiotics. Most amide bonds present in the cystobactamids link benzoic acids with anilines and it was found that some of these amide bonds undergo chemical and enzymatic hydrolysis, especially the one linking ring C with ring D. This work reports on the chemical synthesis and biological evaluation of thirteen new cystobactamids that still contain
Design, synthesis, and activity evaluation of broad-spectrum small-molecule inhibitors of anti-apoptotic Bcl-2 family proteins: Characteristics of broad-spectrum protein binding and its effects on anti-tumor activity
than ABT-737 at inhibiting growth in multiple tumor cell lines known to express Bcl-xL, Bcl-2, and Mcl-1 proteins at high levels. Compounds B-11 and B-12 had the strongest anti-tumor activity of any compounds we produced. This study suggests that it is feasible to design small-molecule inhibitorsbased on the structure of Bim BH3, which shows broad-spectrum binding to Bcl-xL, Bcl-2, and Mcl-1 proteins

Compounds of the formula (I) provide pharmacological agents which lower intracellular glucocorticoid concentrations in mammals, in particular, intracellular cortisol levels in humans. Therefore, the compounds of the instant invention improve insulin sensitivity in the muscle and the adipose tissue, and reduce lipolysis and free fatty acid production in the adipose tissue. The compounds of the invention lower hepatic glucocorticoid concentration in mammals, in particular, hepatic cortisol concentration in humans, resulting in inhibition of hepatic gluconeogenesis and lowering of plasma glucose levels. Thus, the compounds of the instant invention may be particularly useful in mammals as hypoglycemic agents for the treatment and prevention of conditions in which hyperglycemia and/or insulin resistance are implicated, such as type-2 diabetes. The compounds of the invention may also be used to treat other glucocorticoid associated disorders, such as Syndrome-X, dyslipidemia, hypertension and central obesity. The invention furthermore relates to the use of the compounds according to the invention for the preparation of medicaments, in particular of medicaments useful for the treatment and prevention of glucocorticoid associated disorders, by improving insulin sensitivity, reducing plasma glucose levels, reducing lipolysis and free fatty acid production, and by decreasing visceral adipose tissue formation.
