synthesis of new cyclic and acyclic nucleoside analogues was achieved by alkylation of 5-halogenated 6-(2,4-dichlorophenoxymethyl)pyrimidine-2,4-dione following the Vorbrüggen coupling procedure. Nucleoside analogues of the 1-[(2-hydroxyethoxy)methyl]-6-(phenylthio)thymine (HEPT)-type were obtained as well as analogues of ganciclovir, acyclovir, and ribonucleosides. All compounds were tested against

Series of novel 3-(2,4-dichlorophenoxymethyl)-1-phenyl-1H-pyrazole derivatives with various substituents at positions 4 and 5 were synthesized. Antitumor activity of all the synthesized compounds was evaluated by using SRB assay on four cell lines: lung carcinoma (A549), human hepatocellular carcinoma (HepG2), colon carcinoma (HCT116) and mammary gland breast cancer (MCF-7) cell lines. Some of the
