A possible reason for the delayed acceptance of the Internet as a retail distribution channel may be the lack of trust consumers have in the electronic channel and in the Web merchants. Few prior studies on the adoption of business-to-consumer e-commerce have considered trust in information technology as an important determinant of adoption behavior. This(More)
Studies on the adoption of business-to-consumer e-commerce have not simultaneously considered trust and risk as important determinants of adoption behavior. Further, trust in information technology has not been addressed to a great extent in the context of e-commerce. This research explicitly encompasses the electronic channel and the firm as objects to be(More)
Vascular endothelial growth factor (VEGF) is a potent angiogenic peptide. A great deal of interest has been paid to the predictive value of neoangiogenesis represented by microvessel density (MVD), on clinical progression and prognosis of several types of tumors. Serum VEGF levels may therefore be clinically useful for the prediction of increase in tumor(More)
A series of substituted benzophenone analogues, (2-aroyl-4-methylphenoxy)acetamides 4a-e, have been synthesized via three-step synthesis sequence beginning with the 2-hydroxybenzophenones 1a-e in excellent yield. 1a-e on reaction with ethyl chloroacetate afford ethyl (2-aroyl-4-methylphenoxy)acetates 2a-e which on alkaline hydrolysis afforded(More)
A novel series of benzoic acid N'-[2-(4-benzothiazol-2-yl-piperazin-1-yl)-acetyl]-hydrazides 6a-j were synthesized and characterized by IR, (1)H, (13)C NMR, elemental and mass spectral analyses. The in-vitro cytotoxicity and cell viability assay of the synthesized compounds 6a-j were evaluated against Dalton's lymphoma ascites (DLA) cells. Our results(More)
Short chain fatty acids including butyrate exhibit wide variety of biological effects towards cell growth, morphology and gene expression. In this report, we study the mechanism by which butyrate (BuA) modulates the expression of protein phosphatase when treated to the cells. As a model system, we used Ehrlich Ascites Tumor (EAT) cells in which(More)
A sequence of coumarin analogs 5a-j was obtained by multi step synthesis from hydroxy benzophenones (1a-j). The in vitro antiproliferative effect of the title compounds was tested against Ehrlich ascites carcinoma (EAC) and Daltons lymphoma ascites (DLA) cell lines. Among the series, compound 5c with bromo group in the benzophenone moiety was endowed with(More)
Sp1 is a ubiquitous transcription factor and master regulator of various eukaryotic gene expression. Better understanding of the role of increased Sp1 levels on angiogenic regulation and the regulatory regions of that transcription factor may act as a useful target in 'transcriptional therapy'. At the molecular level, butyrate inhibits Sp1-DNA binding(More)
