    Notes: Abstract. The new monomer, 5′-O-methacryloyl-3′-azido-3′-deoxythymidine (MAZT), was synthesized from methacryloyl chloride (MAC) and 3′-azido-3′-deoxythymidine (AZT). The homopolymer of MAZT and copolymers of MAZT with acrylic acid (AA) or exo-3,6-epoxy-1,2,3,6-tetrahydrophthalic glycinylimide (ETGI) were synthesized by radical polymerizations. The structures of MAZT and polymers were confirmed identified by FT-IR and 1H-NMR spectroscopies. The number average molecular weights (M¯n) and polydispersity indices of the synthesized polymers were in the range of 4,400 ∼ 20,400 and 1.2 ∼ 2.0. The in vitro cytotoxicities of polymers against K562 human leukemia and normal cell lines were greater than that of control.

    Notes: The new monomer, α-methoxy-3,6-endo-methylene-1,2,3,6-tetrahydrophthaloyl-5-fluorouracil (MMTFU), was synthesized from 5-fluorouracil (5-FU) and α-methoxy-3,6-endo-methylene-1,2,3,6-tetrahydrophthaloyl chloride (MMTC). Poly(α-methoxy-3,6-endo-methylene-1,2,3,6-tetrahydrophthaloyl-5-fluorouracil) [poly(MMTFU)], poly(α-methoxy-3,6-endo-methylene-1,2,3,6-tetrahydrophthaloyl-5-fluorouracil-co-acrylicco-AA), and poly(α-methoxy-3,6-endo-methylene-1,2,3,6-tetrahydrophthaloyl-5-fluorouracil-co-vinyl acetate) [poly(MMTFU-co-VAc)] were synthesized by photopolymerizations using 2,2-dimethoxy-2-phenylacetophenone (DMP) as the photoinitiator. The synthesized MMTFU and the polymers were identified by FT-IR, 1H-NMR, and 13C-NMR spectroscopies. The contents of MMTFU in poly(MMTFU-co-AA) and poly(MMTFU-co-VAc) determined by elemental analysis were 63 and 57 mol %, respectively. The number average molecular weights and polydispersity indices of synthesized polymers determined with GPC were in range of 7,700-19,100 and 1.6-2.7. The in vitro cytotoxicities of samples were evaluated with mouse mammary carcinoma (FM3A), mouse leukemia (P388), and human histiocytic lymphoma (U937) as cancer cell lines and mouse liver cells (AC2F) as a normal cell line. The cytotoxicities of 5-FU and synthesized samples against cancer cell lines increased in following orders: 5-FU 〉 MMTFU 〉 poly(MMTFU) 〉 poly(MMTFU-co-AA) 〉 poly(MMTFU-co-VAc). The in vivo antitumor activities of the synthesized samples against mice bearing the sarcoma 180 tumor cell line were evaluated. The in vivo antitumor activities of the polymers were greater than that of 5-FU at a dose of 80 mg/kg. © 1998 John Wiley & Sons, Inc. J Polym Sci A: Polym Chem 36: 1625-1632, 1998

    Notes: The new monomer, α-methoxy-exo-3,6-epoxy-1,2,3,6-tetrahydrophthaloyl-5-fluorouracil (METFU), was synthesized by the reaction of 5-fluorouracil (5-FU) and exo-3,6-epoxy-1,2,3,6-tetrahydrophthalic anhydride (ETA) in order to prepare polymers containing 5-FU moiety. Poly(α-methoxy-exo-3,6-epoxy-1,2,3,6-tetrahydrophthaloyl-5-fluorouracil) [poly(METFU)], poly(α-methoxy-exo-3,6-epoxy-1,2,3,6-tetrahydrophthaloyl-5-fluorouraci-co-acrylic acid) [poly(METFU-co-AA)], and poly(α-methoxy-exo-3,6-epoxy-1,2,3,6-tetrahydrophthaloyl-5-fluorouracil-co-vinyl acetate) [poly(METFU-co- VAc)] were synthesized by photopolymerizations using 2,2-dimethoxy-2-phenylacetophenone (DMP) as an initiator. The synthesized METFU and the polymers were identified by FTIR and 1H-NMR spectroscopies. The contents of METFU in poly(METFU-co-AA) and poly(METFU-co-VAc) determined by elemental analysis were 52 and 60 mol %, respectively. The average molecular weights and polydispersity indices determined with GPC were as follows: Mn = 9,400, Mw = 11,400 Mw/Mn = 1.21 for poly(METFU), Mn = 14,400, Mw = 26,800, Mw/Mn = 1.86 for poly(METFU-co-AA), and Mn = 23,100, Mw = 33,000, Mw/Mn = 1.43 for poly(METFU-co-VAc). The in vitro cytotoxicities of samples were evaluated with mouse mammary carcinoma (FM3A), mouse leukemia (P388), and human histiocytic lymphoma (U937) as cancer cell lines, and mouse liver cells (AC2F) as a normal cell line. The in vivo antitumor activities of synthesized polymers against mice bearing the sarcoma 180 tumor cell line were greater than those of 5-FU at concentrations of 0.8 and 80 mg/kg. © 1998 John Wiley & Sons, Inc.
