Synthesis of echiguanine analogs and their ribofuranosyl glycosides that inhibit phosphatidylinositol 4-kinase
摘要:
N-carboxamide-substituted 7-deazaguanine-7-carboxamides and their ribofuranosyl compounds have been synthesized as echiguanine derivatives, and evaluated for inhibition of phosphatidylinositol (PI) Q-kinase. The ethylamide derivative and the corresponding ribofuranosyl compound inhibited PI 4-kinase with IC50 values of 0.02 and 2.4 mu g/ml, respectively. The latter was suggested to also inhibit the enzyme in cultured human epidermoid carcinoma cells. (C) 1997 Elsevier Science Ltd.

N-Substituted-2-amino-4(3H)-7H-oxopyrrolo[2,3-d]pyrimidine-5-carboxamides and their ribofuranosyl and 2',3'-dideoxyribofuranosyl derivatives were prepared as membrane permeable echiguanine analogs and tested for their ability to inhibit phosphatidylinositol (PI) 4-kinase. Compounds 5 and 6 were found to inhibit the enzyme approximately at the same level as echiguanines A and B. It is noteworthy that ribofuranosides 18, 19, and 20 and dideoxyribofuranoside 29 effectively inhibited PI 4-kinase. Thus, the terminal amide and related structures may be preferable for inhibition of the enzyme in echiguanine analogs with or without ribofuranoside. (C) 1998 Elsevier Science Ltd.

An efficient synthesis which utilizes a palladium catalyzed carbonylation reaction between 2-pivaloyl-7-iodo-7-deazaguanine and 3-aminopropionitrile as a keystep was developed for the preparation of a new class of pyrrolopyrimidine based PI4-Kinase inhibitors: Echiguanines A and B.
