Paragraph 0098, (2018/10/27)
PROBLEM TO BE SOLVED: To prepare analgesics, hypnotic agents, anticonvulsant agents, antiepileptics, antiparkinson drugs, dementia prophylactics, and health care food. SOLUTION: The present invention relates to an N6-substituted adenosine derivative and an N6-substituted adenine derivative selected from the group consisting of specific compounds. The present invention also relates to a pharmaceutical composition at least comprising a therapeutically effective amount of the compounds and a pharmaceutically acceptable carrier. The invention further relates to the compounds used in preparation of analgesics, hypnotic agents, anticonvulsant agents, antiepileptics, antiparkinson drugs, dementia prophylactics, and health care food.

ecto-5′-Nucleotidase (eN, CD73) catalyzes the hydrolysis of extracellular AMP to adenosine. eN inhibitors have potential for use as cancer therapeutics. The eN inhibitor α,β-methylene-ADP (AOPCP, adenosine-5′-O-[(phosphonomethyl)phosphonic acid]) was used as a lead structure, and derivatives modified in various positions were prepared. Products were tested at rat recombinant eN. 6-(Ar)alkylamino substitution led to the largest improvement in potency. N6-Monosubstitution was superior to symmetrical N6,N6-disubstitution. The most potent inhibitors were N6-(4-chlorobenzyl)- (10l, PSB-12441, Ki 7.23 nM), N6-phenylethyl- (10h, PSB-12425, Ki 8.04 nM), and N6-benzyl-adenosine-5′-O-[(phosphonomethyl)phosphonic acid] (10g, PSB-12379, Ki 9.03 nM). Replacement of the 6-NH group in 10g by O (10q, PSB-12431) or S (10r, PSB-12553) yielded equally potent inhibitors (10q, 9.20 nM; 10r, 9.50 nM). Selected compounds investigated at the human enzyme did not show species differences; they displayed high selectivity versus other ecto-nucleotidases and ADP-activated P2Y receptors. Moreover, high metabolic stability was observed. These compounds represent the most potent eN inhibitors described to date.

Four classes of 6-X-benzylated purine nucleosides, (i) 6-N-(substituted- benzyl)adenosines, (ii) 6-N-(4-nitrobenzyl)adenine nucleosides with modified sugars, (iii) 6-N(S)-(4-azidobenzyl) derivatives of adenosine, 6-thioinosine, and 6-thioguanosine, and (iv) 6-N-{4-N-[acyl(sulfonyl)amino]benzyl} adenosines, were synthesized and their binding interactions with 'es-NT' (equilibrative, inhibitor-sensitive nucleoside transport) systems were studied. Several tight-binding analogues were found.
