Abundance of proline (Pro) in collagen molecule led us to investigate whether Pro supply affects collagen biosynthesis in human skin fibroblasts. Treatment of the cells with milimolar concentrations (5 and 10 mM) of Pro for 24 and 48 h contributed to increase in alpha1 subunit of collagen type I (COL1A1) expression in both cells and culture medium. However, the effect was more pronounced in glutamine-free medium. In such condition, Pro induced collagen expression by about twofold in the cells, while in the medium only by about 30% during 24 h incubation, compared to control. In the presence of glutamine (Gln), exogenous Pro stimulated intracellular collagen expression only by about 30% during 24 h of fibroblasts incubation, and it was not accompanied by adequate increase of collagen secretion into medium. Gln alone stimulated the processes by about 2?3 fold during the course of the experiment. Pro-dependent increase in collagen expression in Gln-free medium was accompanied by increase in prolidase activity and expression of pAkt. In both Gln-free medium and Gln-supplemented medium, Pro induced expression of p53 and HIF-1alpha. The data suggest that availability of Gln, as a substrate for Pro biosynthesis, determine the utilization of exogenous Pro for the collagen biosynthesis.

The heterogeneously catalyzed diastereoselective hydrogenation of furan-2-carboxylic acid derivatives modified with chiral auxiliaries is described. Chiral auxiliaries, catalysts, solvents, and additives were optimized for the reaction. Finally, the hydrogenation of furan-2-yl-[(S)-2- (hydroxydiphenylmethyl)-pyrrolidin-1-yl]-methanone resulted in a high diastereoselectivity. Removal of the auxiliary gave the tetrahydrofuran-2- carboxylic acid in 95% ee. Georg Thieme Verlag Stuttgart.

Abstract Whole cell based screens to identify hits against Mycobacterium tuberculosis (Mtb), carried out under replicating and non-replicating (NRP) conditions, resulted in the identification of multiple, novel but structurally related spiropiperidines with potent antitubercular properties. These compounds could be further classified into three classes namely 3-(3-aryl-1,2,4-oxadiazol-5-yl)-1?-alkylspiro[indene-1,4?-piperidine] (abbr. spiroindenes), 4-(3-aryl-1,2,4-oxadiazol-5-yl)-1?-alkylspiro[chromene-2,4?-piperidine] (abbr. spirochromenes) and 1?-benzylspiro[indole-1,4?-piperidin]-2(1H)-one (abbr. spiroindolones). Spiroindenes showed ?4 log10 kill (at 2-12 muM) on replicating Mtb, but were moderately active under non replicating conditions. Whole genome sequencing efforts of spiroindene resistant mutants resulted in the identification of I292L mutation in MmpL3 (Mycobacterial membrane protein Large), required for the assembly of mycolic acid into the cell wall core of Mtb. MIC modulation studies demonstrated that the mutants were cross-resistant to spirochromenes but not to spiroindolones. This Letter describes lead identification efforts to improve potency while reducing the lipophilicity and hERG liabilities of spiroindenes. Additionally, as deduced from the SAR studies, we provide insights regarding the new chemical opportunities that the spiroindolones can offer to the TB drug discovery initiatives.

A transition-metal-free protocol for the redox-neutral light-induced decarboxylative coupling of carboxylic acids with (hetero)aromatic nitriles at ambient temperature is presented. A broad scope of acids and nitriles is accepted, and alcohols can be coupled in a similar fashion through their oxalate half esters. Various inexpensive sources of UV light and even sunlight can be used to achieve this C-C bond formation proceeding through a free radical mechanism.

We recently discovered that 5, 8-O-dimethyl acylshikonin derivatives displayed the selectivity towards MCF-7 and no toxicity to normal cells. Herein, a series of the corresponding 6-isomers of 5, 8-O-dimethyl acylshikonin derivatives were synthesized starting from shikonin. In vitro evidence of the cytotoxicities indicated that most of thecompounds were more active than or comparative to shikonin and retained the selectivity against MCF-7, MDA-MB-231 besides no toxicity in the normal cells. Also, in vivo anticancer activity of the positional isomers 5p, 6c further showed that 6-isomers of 5, 8-O-dimethyl acylshikonin derivatives were more active than their corresponding 2-isomers. Thus, we may conclude that the position of the side chain of shikonin attached to 5,8-dimethoxy -1,4-naphthoquinone is associated with the antitumor activity.

A high-throughput screen of the NIH molecular libraries sample collection and subsequent optimization of a lead dipeptide-like series of severe acute respiratory syndrome (SARS) main protease (3CLpro) inhibitors led to the identification of probe compound ML188 (16-(R), (R)-N-(4-(tert-butyl)phenyl)-N- (2-(tert-butylamino)-2-oxo-1-(pyridin-3-yl)ethyl)furan-2-carboxamide, Pubchem CID: 46897844). Unlike the majority of reported coronavirus 3CLpro inhibitors that act via covalent modification of the enzyme, 16-(R) is a noncovalent SARS-CoV 3CLpro inhibitor with moderate MW and good enzyme and antiviral inhibitory activity. A multicomponent Ugi reaction was utilized to rapidly explore structure-activity relationships within S1?, S 1, and S2 enzyme binding pockets. The X-ray structure of SARS-CoV 3CLpro bound with 16-(R) was instrumental in guiding subsequent rounds of chemistry optimization. 16-(R) provides an excellent starting point for the further design and refinement of 3CLpro inhibitors that act by a noncovalent mechanism of action.
