A novel straightforward synthesis of 2-imino-4-thiazolines has been performed by reaction of α-bromoketimines with potassium thiocyanate in acetonitrile. Contrary to other syntheses of these heterocycles, no side reactions were observed. The structural as

Paragraph 0120-0125, (2020/03/09)
The invention discloses a method for preparing a 2-aminothiazole compound. The method comprises the following steps: in an organic solvent, carrying out a condensation reaction on thiourea representedby a formula (II) and a ketone compound represented by a formula (III) at 50-120 DEG C for 6-24 h under the catalysis of elemental iodine, and after the reaction is finished, carrying out post-treatment on the reaction solution to obtain the 2-aminothiazole compound represented by a formula (I). According to the invention, the method has characteristics of cheap and easily available reaction rawmaterials, mild reaction conditions, simpleness, no requirement of transition metal catalysts and a stoichiometric halogenating reagents and cost reducing, and can be used for synthesizing a series of2-aminothiazole derivatives, and the prepared products can be used as important intermediates for synthesizing thiazole structure-containing drugs or bioactive compounds.

Using reported glutathione S-transferase omega 1 (GSTO1-1) cocrystal structures, we designed and synthesized acrylamide-containing compounds that covalently bind to Cys32 on the catalytic site. Starting from a thiazole derivative 10 (GSTO1-1 IC50 = 0.6 μM), compound 18 was synthesized and cocrystallized with GSTO1. Modification on the amide moiety of hit compound 10 significantly increased the GSTO1-1 inhibitory potency. We solved the cocrystal structures of new derivatives, 37 and 44, bearing an amide side chain bound to GSTO1. These new structures showed a reorientation of the phenyl thiazole core of inhibitors, 37 and 44, when compared to 18. Guided by the cocrystal structure of GSTO1:44, analogue 49 was designed, resulting in the most potent GSTO1-1 inhibitor (IC50 = 0.22 ± 0.02 nM) known to date. We believe that our data will form the basis for future studies of developing GSTO1-1 as a new drug target for cancer therapy.
