Interaction of guanine phosphonomethoxyalkyl derivatives with GMP kinase isoenzymes. Biochemical pharmacology, 2000, Dec-15, Volume: 60, Issue:12 Substrate activity and inhibitory potency of guanine phosphonomethoxyalkyl derivatives towards GMP kinase isoenzymes from L1210 cells were studied. 9-[2-(Phosphonomethoxy)ethyl]guanine (PMEG) and the (R)- and (S)-enantiomers of both 9-[3-hydroxy-2-(phosphonomethoxy)propyl]guanine (HPMPG) and 9-[2-(phosphonomethoxy)propyl]guanine (PMPG) were phosphorylated to the first step. Kinetic data showed that (R)-PMPG was a good substrate with a relative phosphorylation efficacy of 12% compared with the natural substrate GMP, whereas PMEG was a poor substrate with a relative phosphorylation efficacy of 1.1%. The structurally related 2,6-diaminopurine analogues 9-[2-(phosphonomethoxy)ethyl]-2, 6-diaminopurine (PMEDAP) and (R)- and (S)-9-[2-(phosphonomethoxy)propyl]-2,6-diaminopurine (PMPDAP) were not phosphorylated by any of the GMP kinase isoenzymes tested. The inhibitory activities of the individual compounds on GMP kinase isoenzymes decreased in the following order: (S)-HPMPG > (R)-PMPG > PMEG > (R)-HPMPG > (S)-PMPG > PMEDAP = (R)-PMPDAP = (S)-PMPDAP; each compound exerted a different type of inhibition.

The effect of purine phosphonomethoxyalkyl derivatives on DNA synthesis in CHO Chinese hamster cells. Neoplasma, 1993, Volume: 40, Issue:6 The inhibition of incorporation of 3H-thymidine and the changes of the rate of nascent DNA chain elongation were investigated in CHO Chinese hamster cells treated with (S)-(3-hydroxy-2-phosphonomethoxypropyl) (HPMP) and N-(2-phosphonomethoxyethyl) (PME) derivatives of adenine (A), guanine (G) and 2,6-diaminopurine (DAP). No direct correlation was observed in PME and HPMP derivatives between cytotoxicity, inhibition of 3H-thymidine incorporation and inhibition of nascent DNA chain elongation. The highest cytotoxicity and inhibition of DNA synthesis were caused by PMEG. The limited extent of inhibition of DNA elongation was encountered in the case of HPMPG and HPMPA. With PMEA, weak inhibition of elongation of DNA was observed only after a prolonged exposure (6 h). None of the investigated drugs induced DNA breaks.

The effect of purine phosphonomethoxyalkyl derivatives on DNA synthesis in CHO Chinese hamster cells.

Neoplasma, 1993, Volume: 40, Issue:6

The inhibition of incorporation of 3H-thymidine and the changes of the rate of nascent DNA chain elongation were investigated in CHO Chinese hamster cells treated with (S)-(3-hydroxy-2-phosphonomethoxypropyl) (HPMP) and N-(2-phosphonomethoxyethyl) (PME) derivatives of adenine (A), guanine (G) and 2,6-diaminopurine (DAP).
