Secondary amines: Synthesis and effect of length of spacer linking two phenyl rings on biological activity

experimental part, p. 1041 - 1044 (2009/12/24)
N-Benzyl benzylamines (1a-11a) and N-benzyl anilines (1b-11b) were synthesized by sodium borohydride reduction of aldimines of benzylamine and aniline respectively. The products were characterized on the basis of elemental analysis and spectral studies and screened for antifungal potential against four fungi and evaluated for nematicidal activity against two nematodes. The former compounds were found to be more effective as compared to the latter thus indicating an enhancement of biological activity due to introduction of an extra methylene group between two phenyl rings of aromatic secondary amines.

The cardiovascular and antithrombotic agent dipyridamole (DP) has potential therapeutic utility as a modulator of the activity of antimetabolite antitumor agents by virtue of its inhibition of nucleoside transport. However, the activity of DP can be compromised by binding to the acute phase serum protein, α1-acid glycoprotein (AGP). Analogues of DP were synthesized and evaluated as inhibitors of 3H-thymidine uptake into L1210 leukamia cells in the presence and absence of 5 mg/mL AGP. Compounds with potency similar to that of DP were identified where the piperidino substituents at the 4,8-positions were replaced by 4?-methoxybenzylamino, 3?,4?-dimethoxybenzylamino, or piperonylamino groups. Replacement of the diethanolamino groups at the 2,6-positions of DP by alkylamino or alkoxy substituents was tolerated, although at least one oxygen-bearing function (hydroxyl or alkoxy) was required in the side chain for activity comparable to that of DP. Whereas AGP completely ablated the activity of DP, the majority of the newer compounds synthesized retained significant activity in the presence of excess AGP, although replacement of the piperidino groups at the 4,8-positions by N-methylbenzylamino substituents did, in some cases, restore susceptibility to AGP. Selected compounds have been demonstrated to prevent rescue from antifolate cytotoxicity, mediated by nucleoside salvage.
