New series of pyrazolo[1,5-α]pyrimidine derivatives 7a-i,11a-c and Schiff bases 13a-c were synthesized and screened for their in vitro antitumor activity against three human carcinoma cell lines,namely colorectal carcinoma（HCT116）,prostate adenocarcinoma（PC-3） and liver carcinoma（HepG-2） using mTT cytotoxicity assay at 100 μg/*** of the tested compounds displayed good anticancer activities against HCT-116 and PC-3 ***,compounds 7d and 11 a showed better antitumor activity than the rest of the compounds against both cell lines.A structure-activity relationship（SAR） has been discussed and structures of the newly synthesized compounds were confirmed by different spectral data（mS,IR,^1H NmR and ^13C NmR） and elemental analysis.

This study was conducted to evaluate the ef fect of replacing soybean meal(SBm) by low protein ?oc meal(LPfm; 24% CP) in tilapia diets on growth performance, feed utilization and ?sh chemical composition. Three isonitrogenous and isocaloric diets were formulated; control diet(C; without LPfm),fm 25(25% of SBm protein was substituted by LPfm) and fm 50(50% of SBm protein was substituted by LPfm). Nine 55 l circular plastic tanks were stocked by 12 ?sh to form three experimental *** dif ferences in tilapia performance were observed between the control and the fm 25 diet. Chemical composition of ?sh did not dif fer signi?cantly among treatments except for protein and selenium contents where the highest values were recorded in the control treatment. The highest mineral content was recorded in ?oc collected from the control tanks, while calcium content showed its highest value in ?oc collected from.f. 50 e ? uent. These data indicate that replacing soybean meal with LPfm up to 25%, had no negative ef fect on growth performance and potentially may improve the system sustainability. meanwhile, the adverse ef fect of more inclusion of LPfm in tilapia diet may be attributed to the higher content of ash. In other word,minerals seem to cause more energy utilization in ?sh fed ?oc meal since it is needed to maintain osmotic homeostasis.
