Novel carbonic anhydrase isozymes I, II and IV activators incorporating sulfonyl-histamino moieties
摘要:
Sulfonylamido(ureido) derivatives of histamine were synthesized by an original procedure in order to obtain tight-binding activators of the zinc enzyme carbonic anhydrase (CA), exploiting the binding energy of the alkyl/arylsulfonyl moieties with amino acid residues at the entrance of the active site. In contrast to the lead molecule, histamine, the new derivatives possessed higher affinity for three different CA isozymes, as evidenced by compairing the affinity constants of these compounds for isozyme CA II.

描述了一种快速高效合成2-(氯磺酰基)苯甲酸甲酯的方法,该方法包括在三入口流动反应器中通过交叉接头对2-氨基苯甲酸甲酯进行连续流重氮化,然后在串联釜反应器中进行氯磺酰化。 。即使在高浓度的盐酸下,该连续流动过程也显着降低了副反应如水解。2-氨基苯甲酸甲酯的质量流量为4.58 kg / h,相当于重氮盐溶液的通量为18.45 kg / h。通过该方法成功地证明了通过在流动反应器中进行反应来抑制平行副反应的潜力。

Organic thiol compounds based on pentaerythritol and dipentaerythritol are described herein. More specifically, the compounds of the present invention are mixed esters of pentaerythritol and dipentaerythritol having at least one sulfhydryl group and preferably a plurality of sulfhydryl groups as well as at least one non-thiol-containing group. The organic thiol compounds are utilized to plasticize and/or heat stabilize halogen-containing polymer compositions especially poly(vinyl chloride) compositions. The compositions are substantially free or free of metal-based stabilizers, Lewis acids and terpenes. The compounds of the present invention are ideally utilized in polymers normally susceptible to deterioration and color change which can occur during processing of the polymer or exposure of the polymer to certain environments and surprisingly also serve as excellent plasticizers.
Compounds and compositions comprising compounds that modulate pyruvate kinase M2 (PKM2) are described herein. Also described herein are methods of using the compounds that modulate PKM2 in the treatment of cancer.
