A set of novel naphthalene derivatives was synthesized via investment of the electrophilic reaction center of the easily obtainable starting substance, 2-cyano-3-(naphthalen-1-yl)acryloyl chloride (1), with various nitrogen nucleophiles and assessed as potential antitumor agents. The chemical structures of these derivatives were completely specified using several spectral and elemental analyses. The antiproliferative efficacy of the discovered compounds against the human cancer cell lines HepG2 and MCF-7 was investigated.

Methods: In this regard, 14 novel benzoxazinone derivatives were synthesized and examined for anticancer activity against two human epithelial cancer cell lines; breast MCF-7 and liver HepG2 cells. 6,8-Dibromo-2- ethyl-4H-benzo[d][1,3]oxazin-4-one was subjected to react with nitrogen nucleophiles to afford quinazolinone derivatives and other related moieties (3-12).
The aim of the present study was to assess the frequency of intestinal parasitic infection among patients with gastrointestinal tract disorders from the Greater Cairo region, Egypt. In addition, a comparison was made of the accuracy of direct thin and thick smear, formol-ether sedimentation (FEC), centrifugal flotation (CF), and mini-FLOTAC techniques in the diagnosis of infection. Out of 100 patients, the overall prevalence of parasitic infection was 51%.
