Salicylanilide esters of N-protected amino acids as novel antimicrobial agents

A series of novel, highly antimicrobial salicylanilide esters of N-protected amino acids were synthesized and characterized. Their in vitro antimicrobial activity against eight fungal strains and Mycobacterium tuberculosis was determined. The compounds had the highest level of activity against Aspergillus fumigatus, Absidia corymbifera and Trichophyton mentagrophytes, and these levels were higher than that of the standard drug fluconazole. In addition, three compounds showed interesting antituberculosis activity, with inhibition ranging from 89% to 99%. (S)-4-Chloro-2-(4-trifluoromethylphenylcarbamoyl)-phenyl 2-benzyloxy-carbonylamino-propionate had the highest level of both antifungal and antimycobacterial activity. The structure-activity relationships of the new compounds are discussed.

One of the oldest and most widely used commercial enzyme inhibitors is aspirin, Formula: C10H7ClN2, which selectively inhibits one of the enzymes involved in the synthesis of molecules that trigger inflammation. you can also check out more blogs about 20375-65-9

Pyridazinones. 2. Synthesis and Antisecretory and Antiulcer Activities of Thiourea and 2-Cyanoguanidine Derivatives

In an effort to develop new types of antiulcer agents, we synthesized a series of novel 2-– and 2--3-(2H)-pyridazinone derivatives.All target compounds were evaluated for gastric antisecretory activity in the pylorus-lygated rat by the method of Shay, and selected compounds were evaluated in the stress-induced ulcer test in rats.Structure-activity relationships were esthablished.Two series of the compounds had significant activity in antisecretory and/or antiulcer tests.The molecular features essential for the activities are a thiourea group or a 2-cyanoguanidine group, a phenyl group in the C-6 position of the 3(2H)-pyridazinone ring, a four-carbon chain length between the 3(2H)-pyridazinone ring and the functional group, and a methyl group at the N-3 position of the functional group.Among them, the three thiourea derivatives (24, 26, and 38) and the six 2-cyanoguanidine derivatives (61,62,65,75,85, and 86) had the most potent antisecretory and/or antiulcer activities.These compounds are not histamine H2-receptor antagonists.

S-Demethylation of Nitrogen Heterocycles

When 3-chloro-4,5-diaminopyridazine (2) was treated with sodium methylmercaptide in refluxing N,N-dimethylformamide, two heterocycles were formed and isolated, neither of which was the expected 3-methylthio-4,5-diaminopyridazine (3).A thorough spectral analysis of these heterocycles showed them to be 4-methylthioimidazo<4,5-d>pyridazine (5) and imidazo<4,5-d>pyridazine-4-thione (6).N,N-Dimethylformamide was found to provide the one carbon unit required for the formation of 5.The origin of 6 was shown to be a result of S-demethylation of 5.S-Demethylation of 3 could also be effected with sodium methylmercaptide in methyl sulfoxide without the occurrence of annulation.In methyl sulfoxide the process of demethylation was accelerated and occurred at lower temperature.

Convergent synthesis of (-)-mirabazole C using a chloroimidazolidium coupling reagent, CIP

Convergent synthesis of (-)-mirabazole C (1), a tetra thiazoline/thiazole alkaloid isolated from blue-green alga, has been described. The successive thiazoline rings of (-)-mirabazole C were formed by a single-step cyclization mediated by TiCl4 treatment of tripeptide amide 4. Convergent synthesis of the key intermediate 33 derived from three 2-methylcysteine residues was first achieved using a newly developed coupling reagent, 2-chloro-1,3-dimethylimidazolidium hexafluorophosphate (CIP). The effectiveness of CIP for the coupling of alpha,alpha-dialkyl amino acids and the reaction pathway of the activation were clarified by the syntheses of model peptides containing an alpha,alpha-dimethylamino acid. A practical method of asymmetric synthesis of 2-methylcysteine by alkylation of 2,4-cis-oxazolidinone 23 has also been described.

Synthesis and activity of dipeptides, linked to targeting ligands, as specific NK cell enhancers

Water soluble analogues of the lipophilic immunostimulant, octadecyl D- alanyl-L-glutamine, BCH-527, were synthesized and evaluated for the ability to stimulate natural killer (NK) cells. One of these compounds in which the octadecyl chain of BCH-527 was replaced with a shorter chain alcohol, 6-(D- alanyl-L-glutaminylamino)hexan-1-ol, 9, displayed an in vitro stimulation of NK cells comparable to that of interleukin 2 (IL 2). However, when the hydroxyl of 9 was linked to L-fucose to yield 1-beta-[6-(D-alanyl-L- glutaminylamino)hex-1-yl]-L-fucopyranose (BCH2537, 1), the observed stimulation of NK cells was greater than that observed with IL 2. Further evaluation of these compounds revealed that the improved in vitro activity of BCH-2537 was more Pronounced in vivo. That is, while both compounds significantly increased splenic NK cells, only BCH-2537 significantly increased the activity of these cells in vivo. In terms of a structure- activity relationship, NK cell activity was sensitive to minor structural modifications. It was influenced by conservative substitutions within the dipeptide, the length of the hydrocarbon chain, and the functionality at the end of the chain. No other compound enhanced NK cell activity to the extent exhibited by BCH-2537, although a few were equipotent to 9.
