Effect of 1-(4-amino-2-methyl-5-pyrimidinyl)methyl-3-(2-chloroethyl)-3-nitrosourea hydrochloride on experimental brain tumors.
permits easy passage across the blood-brain barrier. Others have argued that since brain tumors do not possess a blood brain barrier, the lipid solubility of the nitrosoureas can play no robein their therapeutic effectiveness. We have tested ACNU, a water-soluble nitrosourea, for its chemotherapeutic effect in several animal brain tumor models and have compared ACNU to other more lipid-soluble ...
متن کاملSynthesis and Leishmanicidal Activity of 1-[5-(5-nitrofuran-2-yl)-1, 3, 4-thiadiazole-2-yl]-4-benzoylepiperazines
A series of (5-nitrofuran-2-yl)-1, 3, 4-thiadiazole-2-yl derivatives 6a–6e have been synthesized and screened for in vitro anti-leishmanial activity against the promastigote form of L. major. The structure of Schiff bases were confirmed by 1H NMR, IR. Screening results indicate that all of the designed and synthesized final compounds (6a-6e) significantly reduced the viability of promastigotes ...

متن کاملSynthesis, Reactions and Antioxidant Activity of 5-(3', 4'-dihydroxy-tetrahydrofuran-2'-yl)-2-methyl-3-carbohydrazide
In this manuscript, we describe the synthesis of the carbohydrazide 2. Acid-catalyzed condensation with several carbonyl compounds to afford the corresponding carbohydrazide derivatives 3-12. Their acetylation afforded the corresponding acetyl derivatives 13-22. Oxidative cyclization of O-acetyl derivatives 19-22 afforded the corresponding 1,3,4-oxadiazole derivatives 23-2...
متن کاملSynthesis and Antibacterial Evaluation of (S,Z)-4-methyl-2-(4-oxo-5- ((5-substituted phenylfuran-2-yl) methylene)-2-thioxothiazolidin-3-yl) Pentanoic Acids
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...
