The present invention relates to novel phosphonic acid substituted agents and their pharmaceutical compositions. The novel agents are defined by the following formula: (P-Yn1)m1-Q-K-(Q2-(Yn2-P)m2)j wherein Y is -OCO-, NR1CO- or CON(R1)R2-; Q1 and Q2 are substituted or unsubstituted aryl groups; K is H, -NHCONH-, NHCS-NH, -NHCO-R3- or -NHCSR3-CSNH-; provided when K is H, j is 0; j is 0, 1, 2; n1 and n2 are independently 0, 1 or 2; and m1 and m2 are independently an integer from 1-4. |
