Aly et al 36 synthesized a series of 1-glycosyl thio pyrimidines, annulated pyrimidines derivatives, pyrazolo [3,4-d]-pyrimidines, ditetrazolo [1,5-a,1,5'-c] pyrimidines thieno [2,3-d] pyrimidines derivative the antimicrobial were determined in vitro using cup plate and paper disc method. 3 iwona łakomska, marzena fandzloch, application of 1,2,4-triazolo[1,5-a]pyrimidines for the design of coordination compounds with interesting structures and new biological properties, coordination chemistry reviews, 2016, 327-328, 221crossref. In conclusion, the objective of the our present study was to synthesize and investigated the potent antimicrobial activities of some new (z)-2-((5-(4-hydroxybenzylidene)-4-oxo-4,5-dihydrothiazol-2-yl)amino) acid with the hope of discovering new structures that could be used as potent antimicrobial agents.

Pyrimidine derivatives starting from 2‐amino‐3,5‐dicyano‐6‐methoxy‐4‐(4‐methoxy phenyl)pyridine via selective hydrolysis followed by reaction with formates/acid halides the resulted product is a key intermediate for the synthesis of various pyrido[2,3. A series of novel ([1,2,4]triazolo[1,5-c]quinazolin-2-ylthio)carboxylic acids 2a—d and esters 3a—l were synthesized and evaluated for antimicrobial activity alkylation of potassium 2-thio-[1,2,4]triazolo[1,5- c ]quinazoline 1 with halogenocarboxylic acids and its esters proceeded s -regioselectively. With pyridine 2-carboxylic acid & pyridine 3-carboxylic acid [24] but there is no report on transition metal complexes of hydrazine with pyridine-4-carboxylic acid namely isonicotinic acid.

Antimicrobial activity abstract thiophosgenation of sulfonamides 1a-c in the presence of dilute hcl at room temperature furnished the isothiocyanatosulfonamides 2a-c and treatment with aromatic amines gave 1,3-disubstituted thioureas 3a,b. Aldol condensation of 192 with aromatic aldehyde in acetic acid afforded the chalcons 193, which condensed with benzoic acid hydrazide in acetic acid to give the pyrazol derivatives 194 these compounds show highest antimicrobial activity, shown in (scheme 68. As an acid, the pk a of imidazole is 145, making it less acidic than carboxylic acids, phenols, and imides, but slightly more acidic than alcohols the acidic proton is the one bound to nitrogen the acidic proton is the one bound to nitrogen.

Synthesis, reactions and evaluation of the antimicrobial activity of some 4-(p-halophenyl)-4h-naphthopyran, pyranopyrimidine and pyranotriazolopyrimidine derivatives. Introduction: the presence of pyrimidine ring in nucleic acid, uric acid, several vitamins, some purines, and their importance in many biological processes may explain the biological significance of such molecule in the drugs containing them. A higher alkyl ester of p-hydroxybenzoic acid (paraben) with remarkably high and broad antimicrobial activity against yeasts, moulds and bacteria at very low dosage.

  • [1,5-a]pyrimidine and tetrazolo[1,5-a]pyrimidine, were synthesized in the reactions of thioxopyrimidine-6(1 h )-ones with ethyl chloroacetate (under different reaction conditions), thiourea and sodium nitrite.
  • All amides showed higher activity than pyrimidine carboxylic acid, ii-b1 the most active compound was the allyl amide ii-b3 with an ic 50 of 901 µm all compounds were also tested with buche, but did not show significant inhibition (ic 50 1000 µm.
  • Hydrazinolysis of 5 using ethanolic hydrazine hydrate afforded the corresponding acid hydrazide 6 finally, treatment of 1a,b,d with 2-amind-3-cyano-4,5,6,7-tetrahydrobenzo[b]thiophene yielded thieno[2,3-d]pyrimidines 10a-c bearing sulphonamido moieties.
