Abstract
Various substituted 3-amino-1-(2,4-dinitro phenyl)-5-[(5-substituted-1,3,4-oxadiazol-2-yl)amino]-1-H-pyrazole-4-carboxyamide and (5E)-5-[4-(dimethylamino) benzylidene]-3-(5-substituted-1,3,4-oxadiazol-2-yl)-2-phenyl-3,5-di hydro-4H-imidazol-4-one have been synthesised and evaluated for antiinflammatory activity. Structure of these products has been established by IR, ¹H NMR data. Significant activity were observed for some members of the series.

National Institute for Research in Reproductive Health (NIRRH), formerly known as Institute for Research in Reproduction is a premier research institute of the Indian Council of Medical Research (ICMR). It is situated in the vicinity of a number of hospitals and research institutes in central Mumbai.

Troikaa mainly focuses on Novel Drug Delivery Systems (NDDS). The company firmly believes in providing superior therapeutic benefits by improvising the formulations through Innovative Technologies.
Six patents have been filed in various areas of drug delivery. To handle competition, Troikaa adopted various multifaceted strategies to help stand their ground in the competitive market. Another fact that helps us stand out is their high quality products.

With USFDA approvable API facility - Mac-Chem has carved a niche for itself in the exceedingly competitive and quality-conscious sphere of pharmaceuticals manufacturing. The paradigm shift of leading Indian pharmaceutical companies to target low volume and blockbuster products for regulated markets has been the inspiration behind the launch.

ABSTRACT
Tecoma stans flowers have been traditionally used for many ailments including cancer. In the present study, anti cancer activity of methanolic flower extract of T.stans (METS) was evaluated using both in vitro and in vivo methods. METS was subjected to preliminary qualitative phytochemical investigations by using standard procedures. In vitro antitumor activity of METS was evaluated by the MTT assay methodusing Vero and HEP-2 cell lines. Then the extract subjected to in vivo anti cancer activity using Ehrlich ascites carcinoma (EAC) tumor model. The activity was assessed Increase in life span, average increase in body weight, changes in food intake, tumor volume, tumor weight, viable cell count, non viable cell count, PCV, Total cell count and hematological studies. The potency of the extract was compared with standard 5-flurouracil (20 mg/kg i.p.).In in vitro anti cancer activity METS exhibited significant cytotoxic activity against both cell lines even at different concentrations. Oral administration of METS at the dose of 200 and 400 mg/Kg, significantly (p < 0.001) increased the survival time, non viable cell count and decreased the average body weight and food intake, viable cell count of the tumor bearing mice. After 14 days of inoculation, METS was able to reverse the changes in the hematological parameters, protein and PCV consequent to tumor inoculation.The results indicate that METS possess significant antitumor activity on dose dependent manner.
