  • Water-soluble polymer-based cantharimides as potentially selective anti-tumor agents
    Patent number: 8344007
    Abstract: A cantharimide compound may include the backbone of formula (1). R1, R2, R3, and R4 may be independently selected from the group consisting of H, C(O)OR5, C(O)R6, C(O)NR7R8, NR9C(O)R10, N—R11R12, O—R13, S—R14, P(O)(OR15)(OR16), As(O)(OR17)(OR18), SO2R19, SO3R20, and B(OR21). X1 to X4 may be independently selected from the group consisting of nitrogen and carbon, such that X1 to X4 are not all hydrogen. Y1, Y2 and R5 to R21 may be independently selected from the group consisting of hydrogen, C1-12-alkyl, -aryl, heteroaryl, and a bioactive polymer.
