The created mixture was heated on the boiling water bath for several hrs. When chloroacetamides 7a-c were heated with hydrazine hydrate in ethanol, hydrazines 8a-c were acquired inside a moderate to get affordable yields.

Download Dissertation Abstract In recent years, organic heterocyclic compounds have been developed rapidly in the field of organic chemistry, and take an important signification not only in theory but also in practical application aspects.
The compound 4g which has p-anisyl group showed less drug likeness and also the drug score was less. Research in this direction is still going on, to find an alternative drug which can target the malignant tissues, less toxic and affordable by common man.
The other two compounds 4b and 4c have shown good results against both strains tested. Gill, Synthesis, analgesic and anti-inflammatory activities of some novel pyrazolines derivatives, Bioorg.
MIC values of all the triazole derivates 4a—g are excellent and promising because of the presence two pyrazole rings in a single moiety making them more potent towards the bacterial and fungal strains.
Although there are many therapeutic strategies including chemotherapy and radiotherapy, high toxicity and drug resistance limit the positive outcomes in most cases. Lett, 21 In view of these observation and expect to realize the enforcement of many physiological activities, we combined with different heterocycles of isoxazole, pyrazole, thiadiazine into the same molecule and synthesized a series of isoxazole and pyrazole derivatives with novel structures.
From the results, it is apparent that among the title compounds, all of them, have shown excellent to moderate activity at 9. Introduction Thiazoles and pyrazoles happen to be reported to exhibit medicinal activities. It was found that dipole moment, excitation energy, the energy value of LUMO, solvent accessible surface area, and heat of formation were the key molecular descriptors in descriping the cytotoxic effect of those compounds against EAC.
In the latter study, all the compounds were evaluated for the presence of various toxicity parameters like mutagenicity, tumorigenicity, reproductive affective effects, and irritation.
Major work as follows: Hiyama, K Suzuki, H. Ozdemir, Synthesis and antinociceptive activities of some pyrazoline derivatives, Eur. Test organism growth may have the inhibitory action from the test compound and thus, a obvious zone round the disc made an appearance being an symbol of the inhibition from the test organism growth.
Prediction results are valued and color coded [ 2223 ].CHAPTER – III Chemistry of Pyrazoles.
Ph.D. Thesis: pyrazole derivatives were synthesized using silver triflate as catalyst from chalcones by Claisen-Schmidt condensation of appropriate acetophenones with imidazole aldehydes in the presence of aqueous solution of potassium hydroxide and ethanol at.
