    Abstract: A series of new 2-propylpyrido[2,3-d]pyrimidin-4(3H)-one with different substituents at position 3 were syn-thesized by traditional method and Iodine catalyst method. The effect of the newly synthesized compounds was tested as anti-cancer in National Cancer Institute(NCI)in USA. Some of the synthesized compounds exploited potent antitumor activity,... Show More

    Abstract: The inclusion of both zeolites X and zeolite Y significantly affected the dissipation of malathion in water. In the fresh water, malathion degradation followed a pseudo-first order kinetics with concomitant half-life dropping from 8.76 hours in fresh water to 4.44 and 6.65 hours up on the introduction of faujasite X and Y, respectively. Zeolite X h... Show More
