Two new unusual natural pigments were first isolated from the whole herbs of Selaginella tamariscina. The structure of selaginellin A (1) was established as (R,S)-4-[(4'-hydroxy-3-((4-hydroxyphenyl)ethynyl)biphenyl-2-yl)(4-hydroxyphenyl)methylene]-2,5-cyclohexadien-1-one and selaginellin B (2) as (R,S)-4-[(4'-methoxy-4-(methyl)-3-((4-methoxyphenyl)ethynyl)biphenyl-2-yl)(4-methoxyphenyl)methylen...
Oral treatment with ifosfamide results in dose-limiting encephalopathy. Methylene blue is effective in reversal and prophylaxis of this side effect. In the present study, the pharmacokinetics of ifosfamide after iv and po therapy in combination with prophylactic administration of methylene blue were investigated. Nine patients with metastatic non-small cell lung cancer were treated by a combina...
the resistance of antimicrobials has become a global hazard with the irrational use of antibiotics. infection of drug-resistance bacteria seriously threatens human health. currently there is an urgent need for the development of novel antimicrobial agents with new mechanisms and lower levels of toxicity. in this paper, a series of (s,z)-4-methyl-2-(4-oxo-5-((5-substitutedphenylfuran-2-yl) methy...
The preparation of a magnetic core-shell Z-scheme heterojunction Fe 3 O 4 @SiO 2 @TiO -Ce/rGO composite material by sol–gel and hydrothermal methods is described. catalytic activity the photocatalyst doped with metal Ce loaded graphene significantly improved. Under standard experimental conditions (pH = 7, [methylene blue] 10 mg L ?1 , concentration 0.1 g 50 mL ), lead to maximum degradation me...
BACKGROUND Thiazolidine-2, 4-diones (TZDs) have become a pharmacologically important class of heterocyclic compounds since their introduction in the form of glitazones into the clinical use for the treatment of type 2 diabetes. TZDs lower the plasma glucose levels by acting as ligands for gamma peroxisome proliferators-activated receptors. In addition, this class of heterocyclic compounds posse...
