Synthesis and characterization of the new ambidentate O-cholesteryl-O-phenyl phosphorothioate ligand and its organoarsenic derivatives of phenoxarsin-10-yl and phenothiarsin-10-yl phosphorothioate

Facile Fabrication of Bi24O31Br10 Nanosheets with Phosphorus Sulfide Quantum Dots for Highly Photocatalytic Treating Organic Dyes

“…[27] PÀ S (ca. 530 cm À 1 ) and P=S (612 cm À 1 ) signals [28] from PSQDs could be embedded in the strong symmetric stretching vibration of BiÀ O (534 cm À 1 ). The peaks at 1386 cm À 1 (S=O) and 1084 cm À 1 (PÀ O) might be responsible for the partial oxidation of PSQDs during the synthesis.…”

Cytotoxic Activities of O‐Cholesteryl‐O‐Phenyl‐N‐Phenylphosphoramidate and ItsOrganometallic Tin(lV) Derivatives

“…The structural chemistry of phosphorus-based organo tin(IV) derivatives is influenced by the number and nature of organic groups bonded to tin and phosphorus atoms, as well as the type of donor atom (O, S, Se) [7]. Recently, we have reported the preparation of a new ambidentate phosphorothioate ligand, containing a bioactive group, Na[OSPR'R"], [R'= O-Phenyl, R"= O-cholesteryl] [8], that was used for the synthesis of four organometallic tin (IV) (2-5) [9]. In this paper, we report the results of the bioassay of compounds (1)(2)(3)(4)(5), showing that they posses potent antitumor activities against KB (nasopharyngel carcinoma), OVCAR-5 (ovarium carcinoma) and SQC-1 UISO (squamous cell cervix carcinoma).…”
