phthalic acid/neoplasms

Skin tumor promotion induced by 12-O-tetradecanoylphorbol-13-acetate (TPA) was inhibited by a concurrent and topical application of phthalic acid mono-n-butyl ester cupric salt (PAMBCu) in CD-1 mice initiated with 7,12-dimethylbenz[a]anthracene. PAMBCu inhibited TPA-caused epidermal ornithine

Phthalocyanines have been advanced as photosensitizers for the photodynamic therapy of cancer and selectively sulfonated derivatives have shown promise as tumor imaging agents. In order to study the effect of the degree of sulfonation on their biodistribution pattern, we prepared a series of

Owing to the wide application of phthalic acid esters (PAEs) in the manufacturing of plastic products, they are ubiquitous in the marine environment. However, the occurrence of various PAEs in marine organisms from China has not been well characterized. In this study, 341 marine organism samples

The effect of o-phthalic acid (o-PA) on the production of the anti-tumor polyketide compound aspergiolide A by the marine fungus Aspergillus glaucus was investigated. o-PA at 12mM increased the aspergiolide A production by 77%. A combination of 12mM acetate with 12mM o-PA increased the production by

Phthalic anhydride is a highly toxic substance, facing, however, the problem of hydrolysis. In fact, it is rapidly hydrolyzed in aqueous medium, generating phthalic acid as the final product, which is almost harmless to viable cells. Here we describe the 'one pot' condensation reaction for the

BACKGROUND Phthalate, esters of phthalic acid, are mainly applied as plasticizers and cause several human health and environment hazards. The essential oils of Achillea species have attracted a great concern, since several biological activities have been reported from varieties of these medicinal

Butyl benzyl phthalate is a plasticizer added to polymers to give flexibility and softness. It is used extensively in polyvinyl chloride and in cellulose plastics, polyvinyl acetate, polysulfides, and polyurethane. Butyl benzyl phthalate was nominated as part of a class study of phthalates. Previous

Diethylphthalate and dimethylphthalate are used as phthalate plasticizers, in an extensive array of products. The chronic dermal toxicity of diethylphthalate was evaluated in male and female F344/N rats and B6C3F1 mice in 2-year studies. In a series of special studies, the tumor initiation or

Newer varieties of occupational lung diseases primarily due to the vast increase in industrial technology have been reported recently. Preeminent among such newer agents are vinyl chloride (VC) and polyvinyl chloride. Very few cases have been reported, in Europe only, with descriptive

Ten new Pt (II) complexes were synthesized and tested as potential antitumor drugs in vitro on KB human tumour cell line, and in vivo against four experimental tumour systems (P388, L1210, ADJ/PC6A and Yoshida sarcoma). The complexes contained two primary amine ligands (cyclopentylamine) with

Novel amidino-derivatives of phenylene-bisbenzothiazoles were synthesized and tested for their antiproliferative activity against several human cancer cell lines, as well as DNA-binding properties. The synthetic approach used for preparation of isomeric amidino

CDC25 phosphatases play a critical role in the regulation of the cell cycle and thus represent attractive cancer therapeutic targets. We previously discovered the 4-(2-carboxybenzoyl)phthalic acid (NSC28620) as a new CDC25 inhibitor endowed with promising anticancer activity in breast, prostate, and
