Biol. evaluation led to the identification of I [(I) R = Me, R¹ H, R² = R³ = t-Bu; (II) R = Et, R¹ H, R² = R³ = t-Bu], which showed excellent anticancer activities against tested cancer cell lines with IC₅₀ values ranging from 0.32 to 1.57 μM, resp., while exhibiting weak cytotoxicity on the normal cells (human umbilical vein endothelial cell (HUVEC)). Flow cytometric assay for cell cycle and apoptosis revealed that (I) and (II) caused an arrest in the Sub-G1 cell cycle and inhibited proliferation of cancer cells by inducing apoptosis in a dose-dependent manner.

A one-pot protocol for the synthesis of 4-aryl-2-aminothiazoles from the reaction of aromatic ketones, NBS (N-bromosuccinimide) and thioureas under microwave irradiation at 80-85° in PEG (polyethylene glycol)-400 and water as a green reaction medium was developed. The products were obtained in 84-89% yields in 28-32 min. The method had several advantages such as use of green solvent, easy work-up, excellent yield and avoiding use of lachrymatory α-haloketones.

Freidlina, R. Kh. published the artcileThermal telomerization of olefins with silicon hydrides, HPLC of Formula: 14799-94-1, the publication is Khim. i Prakt. Primenenie Kremneorgan. Soedin., Tr. Konf., Leningrad (1961), 1958(6), 72-82, database is CAplus.

Compounds containing Si-H bonds undergo addition reactions with olefins in a steel autoclave at temperatures of 260-300° and at 100-560 atm. with no other catalyst or initiator. Products are of the type Si(olefin)_nH (I), where n = 1-6. The autoclave itself does not appear to act as an initiator by reacting with Cl in chlorosilanes to give metal chlorides, since a similar reaction takes place when no Cl is present in the Si compound The reaction appears to proceed by a free radical route. The influence of temperature and olefin concentration on the product mixture was investigated. With increasing C₂H₄ concentration, where n = 1, the yield of I decreases; where n = 2 or 3, remains the same; where n >3, increases. Increasing temperature in range 285°-400°, with constant (2:1) excess of olefin in mixture, increased the yield of I where n = 1 at expense of n >3; where n = 2 or 3, the yield varied little. For comparison, the reaction was carried out in the presence of certain metallic chlorides. H₂PtCl₆ catalyzes addition reaction at room temperature, but chlorides of Zr, Ti, and Sn, require temperatures ≃200° and give less satisfactory conversion. This reaction appears to proceed via polar intermediates.
