Novel sulfinyl anilino pyrimidine derivative and application thereof in preparation of antitumor drugs
-
Paragraph 0035-0039, (2021/10/16)
The invention relates to the field of medicines. A novel sulfinyl anilino pyrimidine derivative is disclosed, and the structural formula of the novel sulfinyl anilino pyrimidine derivative is as shown in the specification. Compared with an existing L858R/T790M inhibitor and EGFR / ALK double-target-target reference substance, the aniline-based pyrimidine derivative containing the sulfoxide group has better antitumor H 1975 activity compared with ALK the prior art BaF3 inhibitor and the EGFR/ALK double ALK-target reference substance. As proved by human liver microsomal experiments, the aniline-based pyrimidine derivatives containing the sulfoxide group in the invention are compared with the existing anisyl-containing anilino pyrimidine derivatives. There is a great increase in stability.

A novel strategy of cascade radical C(sp2/sp3)-S bond cleavage and group-transfer cyclization is disclosed. Triggered by alkyl radicals, varieties of 2-isocyanoaryl thioethers containing aliphatic, aryl, and heteroaromatic groups can be cleaved and precisely reinstalled to give benzothiazole derivatives. Mechanistic studies reveal that the cascade reaction undertakes an intermolecular pathway, and the inner radical sources (R radicals) exhibit high priority over those of methyl radical origin from di-tert-butyl peroxide.

3-(2-(Alkylthio)phenylazo)-2,4-pentanedione (HL), an O, N, S donor ligand, is used for the synthesis of Ni(II), Pd(II) and Pt(II) complexes. The spectroscopic (IR, UV-Vis, and NMR) data determine the structure. The single crystal X-ray diffraction measurement of [Ni(L)2] and [Pt(L)Cl] has confirmed the structures. Coulometric oxidation of [Ni(L)2] and EPR spectra thereof show formation of Ni(III) state. DFT computation has calculated the electronic configuration and has explained the spectral and redox properties of the complexes. The compounds are screened for their in vitro anti-bacterial activity using Gram-positive and Gram-negative bacteria (Bacillus subtilis UC564, Escherichia coli TG1, Staphylococcus aureus Bang25, Pseudomonas aeruginosa C/1/7, Salmonella typhi NCTC62, Salmonella paratyphi NCTC A2, Shigella dysenteriae 8NCTC599/52, Streptococcus faecalis S2, Vibrio cholerae DN7 and Mricococcus luteus AGD1). The minimum inhibitory concentration is determined for the compounds. The effect of the structure of the investigated compounds on the antibacterial activity is discussed.
