Therapy resistance by evasion of apoptosis is one of the hallmarks of human cancer. Therefore, restoration of cell death by non-apoptotic mechanisms is critical to successfully overcome therapy resistance in cancer. By rational drug design approach, here we try to provide evidence that subtle changes in the chemical structure of spisulosine completely switched its cytotoxic function from apoptosis to autophagy. Our most potent molecule (26b) in a series of 16 synthesized derivatives showed robust autophagic cell death in diverse cancer cells sparing normal counterpart. Compound 26b mediated lethal autophagy induction was confirmed by formation of characteristic autophagic vacuoles, LC3 puncta formation, upregulation of signature autophagy markers like Beclin and Atg family proteins. Altogether, we have detected novel autophagy inducer small molecule which can be tested further for drug discovery research.

Paragraph 0077; 0079, (2021/06/09)
The invention provides a preparation method of chiral alpha-methyl arylethylamine, and relates to the technical field of organic synthesis medicines. Boc-amino acid methyl ester is used as an initial raw material, Boc-amino alcohol is obtained through reduction, Boc-amino alcohol reacts with thionyl chloride and is oxidized through sodium periodate to obtain a sulfonamide compound, and then the sulfonamide compound is reduced through sodium borohydride promoted by lewis acid and a protecting group is removed under the acidic condition to obtain a target compound. According to the method, raw materials are cheap and easy to obtain, a single optical isomer product is obtained by using chiral raw materials, the problem of column chromatography resolution is solved, generation of a large amount of solid wastes and isomers is avoided, atom economy is improved, the product purity is high, the yield is high, and the production cost is effectively reduced. In addition, the mild reduction system is used for replacing the original high-pressure hydrogenation reaction, the process operation is relatively simple, and the method is more suitable for large-scale industrial production.

A series of chiral non-racemic N1,N10-ethylene bridged flavinium salts 4 was prepared using enantiomerically pure 2-substituted 2-aminoethanols (R = isopropyl, phenyl, benzyl, 4-methoxybenzyl, 4-benzyloxybenzyl) derived from amino acids as the sole source of chirality. The flavinium salts were shown to form 10a-hydroperoxy- and 10a-methoxy-adducts with moderate to high diastereoselectivity depending on the ethylene bridge substituent originating from the starting amino acid. High diastereoselectivities (dr values from 80:20 to >95:5) were observed for flavinium salts bearing benzyl substituents attached to the ethylene bridge. The benzyl group preferred the face-to-face (syn) orientation relative to the flavinium unit; thereby effectively preventing nucleophilic attack from one side. This conformation was found to be the most stable according to the DFT calculations. Consequently, the presence of benzyl groups causes intermolecular fluorescence quenching resulting in a significant decrease in the fluorescence quantum yield from 11% for 4a bearing an isopropyl substituent to 0.3% for 4c containing a benzyl group and to a value lower than 0.1% for the benzyloxybenzyl derivative 4e.

supporting information; experimental part, p. 1208 - 1212 (2012/03/11)
A new series of 2-substituted thiazole carboxamides were identified as potent pan inhibitors against all three isoforms of Akt (Akt1, Akt2 and Akt3) by systematic optimization of weak screening hit N-(1-amino-3-phenylpropan-2-yl)- 2-phenylthiazole-5-carboxamide (1). One of the most potent compounds, 5m, inhibited the kinase activities of Akt1, Akt2 and Akt3 with IC50 values of 25, 196 and 24 nM, respectively. The compound also potently inhibited the phosphorylation of downstream MDM2 and GSK3β proteins, and displayed strongly antiproliferative activity in prostate cancer cells. The inhibitors might serve as lead compounds for further development of novel effective anticancer agents.

experimental part, p. 3413 - 3426 (2011/02/26)
Enantiomerically enriched epoxides are useful intermediates that have found many applications in asymmetric synthesis, and development of efficient catalysts for asymmetric epoxidation has received considerable attention, In this manuscript we describe the design, preparation, and use of new highly selective imlnium salt organocatalysts for asymmetric epoxidation, based around a chiral binaphthalene motif coupled with a chiral substituted dioxane moiety. The new catalysts have been tested in the catalytic asymmetric epoxidation of unfunctionalized alkenes, and provide up to 95 % ee.
