Four new triphenyltin(IV) complexes of composition Ph(3)SnLH (where LH=2-/4-[(E)-2-(aryl)-1-diazenyl]benzoate) (1-4) were synthesized and characterized by spectroscopic (((1))H, ((13))C and ((119))Sn NMR, IR, ((119))Sn Mössbauer) techniques in combination with elemental analysis. The ((119))Sn NMR

Prostate cancer (PCa) incidence is surging in United States and other parts of the world. Synthetic and natural compounds have been explored as potential modulators of PI3K/Akt signaling that is known to drive PCa growth. Here, we evaluated the efficacy of a series of triphenyltin (IV) carboxylate

Metal complexes with organelle specificity and potent but selective cytotoxicity are highly desirable. A novel series of triphenylstannyl 4-((arylimino)methyl)benzoates (2-8) were obtained by the reactions of triphenylstannyl 4-formylbenzoate [Ph3Sn(L1)] 1 with primary aromatic amines. Two

Bestrabucil (KM2210), the benzoate of an estradiol-chlorambucil conjugate, was used experimental cancer chemotherapy against 13 human tumor xenografts serially transplanted into nude mice, and its pharmacokinetics was studied. The tumors were one esophageal, two gastric, six colon, one cholecystic

KM2210 is a benzoate of an estradiol-chlorambucil conjugate with three active metabolites, KM2202, estradiol (E2) and chlorambucil (CBL). The mode of action of this compound was assessed using MCF-7 human breast tumours transplanted into nude mice. The growth of MCF-7 in nude mice was inhibited by

Previously, we reported a hypoxia-inducible factor (HIF)-1 inhibitor LW6 containing an (aryloxyacetylamino)benzoic acid moiety inhibits malate dehydrogenase 2 (MDH2) using a chemical biology approach. Structure-activity relationship studies on a series of (aryloxyacetylamino)benzoic acids identified

Drug interaction between DIME or DIPE ¿1-[3, 5-diiodo-4-(4'-methoxyphenoxy)-phenyl]-ethanone¿ with vincristine and vinblastine on the growth rate of MDA-MB-231 human mammary cancer cells was determined by the median effect kinetic method. Mutually exclusive cellular binding sites were identified

Thioredoxin reductase (TrxR) is overexpressed in cancer cells and is therefore a putative cancer target. Inhibition of this enzyme is considered an important strategy for the development of new chemotherapeutic agents with a specific mechanism of action. Organotin compounds have been described as

The most potent catechin in green tea is (-)-epigallocatechin-3-gallate [(-)-EGCG], which, however, is unstable under physiological conditions. To discover more stable and more potent polyphenol proteasome inhibitors, we synthesized several novel fluoro-substituted (-)-EGCG analogs, named F-EGCG

A series of radioiodinated benzoate and carbamate esters of cholesterol and pregnenolone wherein the acyl moiety served as the carrier for radioiodine was synthesized and evaluated as potential imaging agents for the adrenal cortex. 2,6-Dimethyl-3-iodobenzoyl and N-(4-iodophenyl) carbamoyl groups

Castrate resistant prostate cancer (CRPC) is associated with increased androgen receptor (AR) signaling often brought about by elevated intratumoral androgen biosynthesis and AR amplification. Inhibition of androgen biosynthesis and/or AR antagonism should be efficacious in the treatment of CRPC.

Topical application of caffeine sodium benzoate (caffeine-SB) immediately after UVB irradiation of SKH-1 mice enhanced UVB-induced apoptosis by a 2- to 3-fold greater extent than occurred after the topical application of an equimolar amount of caffeine. Although topical application of caffeine-SB or

Chemical investigation of Jasminum pentaneurum Hand.-Mazz led to the isolation and identification of 12 compounds, which included one new secoiridoid glycoside, 10-(3-hydroxy-4-methoxy-benzoate)-ligustroside (4), three secoiridoid glycosides (1-3), and eight phenols

The alpha-emitter (211)At labeled to a monoclonal antibody has proven safe and effective in treating microscopic ovarian cancer in the abdominal cavity of mice. Women in complete clinical remission after second-line chemotherapy for recurrent ovarian carcinoma were enrolled in a phase I study. The

Monoclonal antibodies C215, reactive with colorectal carcinomas, and MOv18, reactive with most of the ovarian carcinomas, were radiohalogenated with [211At]astatine. The radiohalogen was conjugate coupled to antibodies via the intermediate labelling reagent
