A new complex has been synthesized of Zn (II) complex with 6-thioguanine and physicochemical characterized by amperometry, polarography elemental analysis, UV and IR spectroscopy. After Synthesis of metal complex, it was evaluated it for antibacterial activities against various pathogenic microorganisms such as; Streptococcus aureus, Proteus. M., klebsiella pneumonia and Asperginus Niger, Nigrosporan S.P. Sarcoma-180 tumor cell has been used for anticancer screening of metal complex for in vitro study. The result of pharmacological studies with M: L revealed that the complex is more potent as compared to the pure drug as regards to its anticancer...

Effect of Vit. E on blood glucose and its possible interactions with oral antidiabetic agents (i.e. glimepiride, gliclazide and metformin) in rabbits have been reported in the present study. The study was performed on albino rabbits in which hyperglycemia was induced by giving glucose. We observed that Vit.E significantly lowered the blood glucose level but on co-administration with oral antidiabetic agents it antagonized the effect of the latter drugs. It is therefore advisable not to give inadvertent amount of Vit.E to diabetic patients just in a belief that antioxidants are helpful to diabetics and do not produce adverse...

Kaempferol and quercetin are the flavonoids which are widespread in fruits and vegetables exhibiting important biological activities. A simple and precise HPTLC method was developed and validated for simultaneous determination of kaempferol and quercetin in herbal drug extracts of Podphyllum hexandrum and Cassia angustifolia. The HPTLC of flavonoids was performed with toluene: acetone: formic acid (7:3:0.25) as mobile phases on RP-18 F254 TLC plates. Densitometric determination of flavonoids was performed at λ = 254 nm in reflectance/ absorbance mode. The results obtained indicated that the developed method was precise and accurate. Good resolution of kaempferol and quercetin was obtained from other constituents present in methanolic and hydrolysed extracts of P. hexandrum and C. angustifolia using proposed HPTLC method. Kaempferol was quantified in free (8.01and 2.42 µg/mg) as well as bound (17.54 and 8.13 µg/mg) forms and quercetin in free (4.5 and 0.93 µg/mg) as well as bound form (6.17and 4.8 µg/mg) in P. Hexandrum and C. angustifolia. Kaempferol was found to be present in high concentration and quercetin was...

Fingerlings of Mystus (M.) vittatus (Bl.) a freshwater siluroid when subjected to a sublethal concentration of 2.4 mg/l hexavalent chromium for 20 days elicited significantly decreased RNA and protein in the liver. However, 10 days of exposure under the same stress produced no significantly alteration neither in the protein content nor in the nucleic acids (DNA, RNA) content of the liver. Results are discussed in relation to pollutional stress of hexavalent...

All the newly synthesized Coumarin derivatives have shown considerable anti-inflammatory activity. In the present research work, we synthesized a series of novel Coumarin derivatives. The Coumarin derivatives such as substituted 7-hydroxy-4-methyl-2H-chromen-2-one and substituted 6-chloro-7-hydroxy-4-methyl-2H-chromen-2-one were synthesized from substituted benzoyl chloride. The chemical structures of the synthesized compounds were confirmed by means of IR and 1H-NMR. These compounds were screened for anti-inflammatory activity by carrageenan induced paw edema method in rats at a dose of 30 mg/kg body weight. All the tested compounds of Coumarin derivatives were found to be more potent when compared to standard drug...
