Orientations of the phenyl group and the intramolecular hydrogen bond play prime roles in the packing patterns of three conformational polymorphs of an unsymmetrical thiourea derivative, 1-(5-methylthiazol-2-yl)-3-phenylthiourea (PTH1). Self-assembly of each polymorph is composed of hydrogen-bonded dimeric motifs held together in head-to-tail arrangement but packed in different manners. Each has an intramolecular N-H…N hydrogen bond between an amide N-H and the nitrogen atom of the 5-methylthiazole unit. The packing pattern of 1-(4-methylthiazol-2-yl)-3-phenylthiourea (PTH2) is composed of dimeric assemblies of PTH2 in head-to-tail fashion. PTH2 is monomorphic as there are intermolecular C-H…S interactions between a C-H bond of the phenyl ring of each molecule and the sulfur atom of the thiocarbonyl group of a neighboring molecule. Such interactions lock the orientation of phenyl group in the solid state. The syn-anti conformation across the thiourea group, originally present in the positional isomers PTH1 and PTH2, is invariably transformed to syn-syn conformation in their salts. The extent of hydration of anions in the salts of PTH1 or PTH2 is dependent on the cation as well as the anion. The chloride salt of PTH1 has a large difference in packing patterns in comparison with the corresponding chloride salt of PTH2; they also differ in the numbers of symmetry-nonequivalent molecules in their respective unit cells. The anhydrous salt of PTH1 with hydrogen bromide having a 1:1 ratio of cation and anion is formed, whereas the bromide salt of PTH2 is a hydrate of composition (HPTH2)2(Br)2¡¤6H2O. This salt has bromide-water clusters in its crystal lattice. Nitric acid reacts with PTH1 under different conditions to form hydrated or anhydrous salts. The hydrated salt (HPTH1)2(NO3)2¡¤H2O has anions bridged by water molecules. The anhydrous nitrate salts of PTH1 and PTH2 are structurally similar in having nitrate…nitrate interactions. The deprotonation of polyacids by PTH1 and PTH2 is selective. The ability to abstract a proton from sulfuric acid to form crystalline salts by PTH1 and PTH2 differs. The sulfate salt (HPTH1)2(SO4) is formed by reaction of sulfuric acid with PTH1, but PTH2 forms the bisulfate salt (HPTH2)HSO4¡¤H2O. PTH1 forms the corresponding dihydrogen phosphate salt upon reaction with orthophosphoric acid; the dihydrogen phosphate anions are held together in the form of cyclic hydrogen-bonded hexameric assemblies in the lattice. Water loss from the assemblies of hydrated salt was determined by thermogravimetry and differential scanning calorimetry and showed that dehydration from anion-assisted assemblies was guided by the cationic host and the type of assembly.

There is an urgent need for structurally novel anti-norovirus agents. In this study, we describe the synthesis, anti-norovirus activity, and structure-activity relationship (SAR) of a series of heterocyclic carboxamide derivatives. Heterocyclic carboxamide 1 (50% effective concentration (EC50)=37 muM) was identified by our screening campaign using the cytopathic effect reduction assay. Initial SAR studies suggested the importance of halogen substituents on the heterocyclic scaffold and identified 3,5-di-boromo-thiophene derivative 2j (EC50=24 muM) and 4,6-di-fluoro-benzothiazole derivative 3j (EC50=5.6 muM) as more potent inhibitors than 1. Moreover, their hybrid compound, 3,5-di-bromo-thiophen-4,6-di-fluoro-benzothiazole 4b, showed the most potent anti-norovirus activity with a EC50 value of 0.53 muM (70-fold more potent than 1). Further investigation suggested that 4b might inhibit intracellular viral replication or the late stage of viral infection.

Herein we describe the synthesis and biological evaluation of a series of novel benzothiazoles based on a diaryl urea scaffold previously reported in some allosteric chemokine receptor 2 (CXCR2) inhibitors. From a library of 41 new compounds, 17 showed significant inhibition of CXCR2, with IC50 values less than 10 mum and selectivity over CXCR4. Our ADMET simulations suggest favorable drug-like properties for the active compounds. Importantly, we developed a predictive model that can distinguish active from inactive compounds; this will serve as a valuable tool to guide the design of optimized compounds to be evaluated in preclinical models.

Meat flavors produced from non-animal source is a promising topic targeting the market demand in special context to vegetarian community. In this research work, key volatiles related to beef like odors were identified from a meat-like flavor system (YE-xylose-cysteine-thiamine). The aroma-active compounds were detected through GC-O-MS. To deduce the formation pathways of key beef-meaty aroma compounds, the carbohydrate module labeling (CAMOLA) experiment was adopted for Maillard reaction. A model study was conducted using the identified peptides, [13C5] xylose/xylose (1:1), cysteine and thiamine. Finally, key beef like aroma compounds were selected through comparing the results of meat-like flavor systems with the model experiment. The detected odorants were mainly divided into pyrazines (6 types), furans (7 types), 2-methylthiophene and 4-methyl-5-hydroxyethylthiazole. The carbon skeleton sources of the compounds were inferred based on GC-MS data from model systems.
