The synthesis and use of oxetane modified dipeptide building blocks in solution and solid-phase peptide synthesis (SPPS) is reported. The preparation of building blocks containing non-glycine residues at the N-terminus in a stereochemically controlled manner is challenging. Here, a practical 4-step route to such building blocks is demonstrated, through the synthesis of dipeptides containing contiguous alanine residues. The incorporation of these new derivatives at specific sites along the backbone of an alanine-rich peptide sequence containing eighteen amino acids is demonstratedviasolid-phase peptide synthesis. Additionally, new methods to enable the incorporation of all 20 of the proteinogenic amino acids into such dipeptide building blocks are reported through modifications of the synthetic route (for Cys and Met) and by changes to the protecting group strategy (for His, Ser and Thr).

Enantioselective formation of cyclohexene derivatives bearing an all-carbon quaternary stereogenic center is described. The racemic cyclohexenes are readily transformed to chiral substituted cyclohexenes in good yield with excellent enantioselectivity and diastereoselectivity by a palladium-mediated deracemization. The resulting products are promising synthetic intermediates of biologically active natural products. This protocol provides us with a new entry to the concise and scalable synthesis of multifunctionalized compounds.

The preparation of ORM-10921, a selective (2C)-adrenoceptor antagonist with promising anti-psychotic properties, was successfully achieved using asymmetric -alkylation of ,-unsaturated imide and Bischler-Napieralski cyclization/asymmetric reduction as the key steps. When the tetracyclic iminium 11S was used in the reduction, the diastereo-selectivity was poor, from which four stereoisomers of ORM-10921 were obtained, respectively. However, the diastereoselectivity could be significantly improved (with dr up to >97:3) when the tricyclic imine substrate 19S was applied in this reduction, suggesting an additional chelation from the side-chain methoxy group in the transition state. According to this protocol, ORM-10921 was accomplished in a highly enantioselective manner. In addition, two analogs 26Aa and 26Ba were prepared using this novel method, and the absolute configurations were unambiguously assigned by single crystal X-ray crystallography.

A series of1,2,4- and 1,3,4-oxadiazole derivatives were synthesized and evaluated for their anticancer activity. Halogenated 1,2,4-oxadiazoles were obtained from benzonitrile and coupled either lipophilic amines or with aminoalcohols. Lipophilic 1,3,4-oxadiazole derivatives were obtained through the Mannich reactions between 5-(aryl)-1,3,4-oxadiazole-2-thiol and alkylated or acylated amines. The in vitro cytotoxic effects were evaluated against 4T1- mammary carcinoma and CT26 – colon cancer cells. The best results were obtained for the 1,3,4-oxadiazole coupled to alkylated piperazine with 10-14 carbon chain moiety, with IC50 values ranging from 1.6 to 3.55 mu M for the 4T1 cell line, and from 1.6 to 3.9 mu M for the CT26.WT cell line, and selectivity index up to 19. The most potent compounds were investigated with AnnexinV and PI staining as indicative of apoptosis induction. (C) 2019 Published by Elsevier Masson SAS.

LDH1A1, one of 19 NAD(P)(+)-dependent aldehyde dehydrogenases, participates in multiple metabolic pathways and has been indicated to play an important role in obesity and diabetes. In this study, a series of 1,3-di-methylpyrimidine-2,4-diones were designed, synthesized and evaluated as novel selective aldehyde dehy-drogenase 1A1 inhibitors. Among them, compounds 46, 50, 53, 56 and 57 exhibited excellent inhibitory activity against ALDH1A1 with IC50 values in the low nanomolar range and high selectivity over ALDH1A2, ALDH1A3, ALDH2 and ALDH3A1.

Piperine is a component of pepper which has earlier been reported as anticancer active compound. This work is emphasized on the design and synthesis of new hybrid piperine analogs by coupling piperine with the amine group of oxadiazoles and thiadiazoles. The new series of twelve piperine analogs was been tested for in vitro anti-proliferative activity using sulforhodamine B (SRB) assay test against MCF-7, PC-3, and HeLa cell lines. Among the twelve synthesised molecules piperine derivative with oxadiazole baring hydroxyl group (3) exhibits the higher activity against MCF-7 cell line than the reference drug Adriamycin and also displays the highest binding energy in the in silico studies. The other analogs are moderately active.

A convenient and efficient strategy for the synthesis of 2-acyl benzothiazoles/thiazoles has been developed. The treatment of benzothiazole/thiazole with allylic Grignard reagents readily generates the corresponding 2-Grignard reagents, which is followed by a reaction with N,N’-carbonyldiimidazole activated carboxylic acids to afford various 2-acyl benzothiazoles/thiazoles products. The synthetic method is applicable to a wide array of carboxylic acids and allows easy access to 2-acyl benzothiazoles/thiazoles with considerable yields under mild reaction conditions.
