Heterogeneous poly (A)-mRNA fraction was isolated from rat liver microsomes using phenol-chloroform extraction, millipore filtration and poly (U)-agarose affinity chromatography. Obtained fractions were characterized with respect to their secondary structure and poly (A) content. Isolated poly (A)-mRNA fraction contained high template activity for glutamate dehydrogenase in cell-free systems with microsomes or polysomes. A spectrophotometric procedure to follow enzyme biosynthesis was also developed.

A heterogeneous poly A-mRNA fraction was isolated from rat liver microsomes by phenol:chloroform extraction, millipore filtration, and poly U-agarose affinity chromatography. The fractions were characterized by their secondary structures and poly A contents. From translational studies, the isolated fraction was found to have high glutamate dehydrogenase template activity in cell-free systems containing microsomes or polysomes. A spectrophotometric procedure for following enzyme biosynthesis was also developed.

Two isosteric analogues of nicotinamide adenine dinucleotide, C-NAD (11) and C-PAD (12), in which the nicotinamide riboside portion is replaced by a C-nucleoside, were synthesized from 5-(beta-D-ribofuranosyl)nicotinamide (7) and 6-(beta-D-ribofuranosyl)picolinamide (8), respectively. Nucleoside 7 was prepared from the 2,3-O-isopropylidene-5-O-(tetrahydropyranyl)-D-ribonolactone (13) and 3-cyano-5-lithiopyridine as reported earlier. Nucleoside 8 was obtained by conversion of the bromo function of the 6-(2,3:4,5-di-O-isopropylidene-D-altro-pentitol-1-yl)-2-bromopyrid ine (14) into a carboxamido group followed by mesylation of the anomeric hydroxyl group to give derivative 18. Treatment of 18 with CF3COOH/CHCl3 caused deisopropylidenation with simultaneous cyclization into the desired 6-(beta-D-ribofuranosyl)picolinamide (8). NAD analogues, C-NAD (11) and C-PAD (12), were synthesized by imidazole-catalyzed coupling of the corresponding 5'-monophosphates of 7 and 8 with the adenosine-5'-monophosphate. Dinucleotide 11 was found to inhibit the proliferation of L1210 cells (IC50 = 7 microM) and to be a good competitive inhibitor of inosine monophosphate dehydrogenase (IMPDH, ID50 = 20 microM) as well as bovine glutamate dehydrogenase (GDH, Ki = 15 microM). Interestingly, C-NAD (11) caused extremely potent noncompetitive inhibition of horse liver alcohol dehydrogenase (ADH, Ki = 1.1 nM), whereas C-PAD (12) was found to be a much less potent competitive inhibitor (Ki = 20 microM) of ADH.
