- METHODS, COMPOSITIONS, AND FORMULATIONS FOR PREVENTING OR REDUCING ADVERSE EFFECTS IN A PATIENT
-
The present invention provides methods, compositions, formulations, and kits related to acadesine, or a prodrug, analog, or salt thereof, and/or a blood clotting inhibitor for preventing or reducing adverse side effects in a patient. The type of patient that may benefit includes a patient with decreased left ventricular function, a patient with a prior myocardial infarction, a patient undergoing non-vascular surgery, or a fetus during labor and delivery.

- Nucleosides and nucleotides. 96. Synthesis and antitumor activity of 5-ethynyl-1-β-D-ribofuranosylimidazole-4-carboxamide (EICAR) and its derivatives
-
The palladium-catalyzed cross-coupling reaction of 5-iodo-1-(2,3,5-tri-O-acetyl-β-D-ribofuranosyl) imidazole-4-carboxamide (8) with various terminal alkynes in the presence of bis(benzonitrile)palladium dichloride in acetonitrile containing triethylamine gave the desired 5-alkynyl derivatives 9 in high yields. However, when (trimethylsilyl)acetylene was used, the only isolable product was the undesired dimer, 1,2-bis(4-carbamoyl-1-β-D-ribofuranosylimidazol-5-yl)acetylene derivative 10a. To circumvent such dimer formation, the reaction was done with use of trimethyl[(tributylstannyl)ethynyl]silane in the absence of triethylamine to afford the desired 5-(2-trimethylsilyl)ethynyl derivative 9a in good yield. Furthermore, the similar cross-coupling reaction of 5-iodo-1-(2,3,5-tri-O-acetyl-β-D-ribofuranosyl) imidazole-4-carbonitrile (12) with (trimethylsilyl)acetylene also afforded the desired nucleoside 13a. Deprotection of these compounds furnished 5-alkynyl-1-β-D-ribofuranosylimidazole-4-carboxamides (6b-k) and -carbonitriles (14b-f). Among these, 5-ethynyl-1-β-D-ribofuranosylimidazole-4-carboxamide (6b, EICAR) is the most potent inhibitor of growth of the various tumor cells in culture including human solid tumor cells. Preliminary results of in vivo antitumor activity against murine leukemias L1210 and P388 are also described.
