Establishing Dependences between Different Lipophilic Parameters of New Potentially Biologically Active N-Substituted-2-Phenylacetamide Derivatives by Applying Multivariate Methods

Synthesis of Some Nitrogen Functional Derivatives of 5-substituted-6-azauracil as Biologically Active Compounds

3-Arylhydrazono-2,4-dioxo-4-phenylbutanoates have been prepared by the coupling of benzoylpyruvate with aryldiazonium chlorides. Reactions of the 3-arylhydrazono-2,4- dioxo-4-phenylbutanoates with 1-aminoguanidine, semicarbazide, and thiosemicarbazide gave 5-substituted 2-imino-6-azauracil (3a), 6-azauracil (3b), and 2-thio-6-azauracil (3c), respectively. The analytical data of these compounds ...

Synthesis of novel, potentially biologically active dibenzosuberone derivatives.

Novel representatives of the important group of biologically active dibenzosuberone derivatives were prepared: 3,7-dibromo-5-(dimethylaminoethyl- oxyimino)-10,11-dihydro-5H-dibenzo[a,d]cyclohepta-1,4-diene (1), 3,7-dibromo-5-(3- dimethylaminopropylidene)-10,11-dihydro-5H-dibenzo[a,d]cycloheptene (2) and 1,7- dibromo-5-(3-dimethylaminopropylidene)-10,11-dihydro-5H-dibenzo-[a,d]-cycloheptene (3)....

Synthesis of Some New Piperazine-iV^iV'-bis-substituted Derivatives As Potential Biologically Active Agents

In a search for new bactericidal and fungicidal agents some new piperazine-TV, TV'-bis-substituted derivatives have been prepared and characterized by their elemental analysis, IR, *H N M R , and mass spectral d a t a . T h e ant ibacter ia l and antifungal activities of all p repared c o m p o u n d s have been determined using Gentamycin as s t a n d a r d antibiotic. Some c o m p o u n d s s...

N-substituted 2-isonicotinoylhydrazinecarboxamides--new antimycobacterial active molecules.

This report presents a new modification of the isoniazid (INH) structure linked with different anilines via a carbonyl group obtained by two synthetic procedures and with N-substituted 5-(pyridine-4-yl)-1,3,4-oxadiazole-2-amines prepared by their cyclisation. All synthesised derivatives were characterised by IR, NMR, MS and elemental analyses and were evaluated in vitro for their antimycobacter...
