• Photochemistry of phenoxybenzyl alcohols in aqueous solution: photosolvolysis vs. photorearrangement to 6H-dibenzo[b,d]pyrans

  The photochemistry of three phenoxybenzyl alcohols (1-3) has been studied in MeOH, CH3CN, and in aqueous solution. It was found that both of the ortho-substituted phenoxybenzyl alcohols 1 and 2 gave the corresponding 6H-dibenzo[b,d]pyrans 6 and 10, via a mechanism believed to involve initial aryl C-O bond homolysis followed by rearrangement to give a 2-(2'-hydroxyphenyl)benzyl alcohol (biphenyl) derivative, which subsequently undergoes a photocyclization reaction to the corresponding 6H-dibenzo[b,d]pyran. The quantum yield for formation of 6 (from 1) was 0.0073 in neutral 6:4 H2O-CH3CN. Lower quantum yields for formation of 6 were observed on photolysis in pure organic solvents (PHI = 0.0015 in 100% CH3CN). The meta-substituted isomer 3 did not give any reaction via a similar photocyclization process: its photochemistry involves initial aryl C-O bond homolysis followed by simple radical recoupling to give isomeric hydroxybiphenyls, as well as products derived from radical escape. In aqueous sulfuric acid solution (pH < 2), a competing acid-catalyzed photosolvolysis reaction was observed for all of these compounds (i.e., C-OH bond heterolysis with assistance of hydronium ion); it was the only observed reaction in moderately concentrated sulfuric acid solution.
• Inhibition of Nucleoside Transport by New Analogues of 4-Nitrobenzylthioinosine:  Replacement of the Ribose Moiety by Substituted Benzyl Groups

  4-Nitrobenzylthioinosine (NBTI, 1) is a well-known inhibitor for the nucleoside transport protein ENT1. However, its highly polar nature is unfavorable for oral absorption and/or penetration into the CNS. In the search for compounds with lower polarity than NBTI we replaced its ribose moiety by substituted benzyl groups. Halogen, hydroxyl, (trifluoro)methyl(-oxy), nitro, and amine functionalities were among the substituents at the benzyl group. In general, substitution of the benzyl group resulted in a lower affinity for ENT1. Only 2-hydroxyl substitution showed a higher affinity. Most likely this is the result of hydrogen bonding. Substitution at the 2-position of the benzyl group with aryl groups was also addressed. Compared to parent compound carrying a 2-phenylbenzyl group, all synthesized analogues gave higher affinities. Introduction of fluoro, trifluoromethyl, methoxy, and hydroxyl groups at the phenyl group clearly showed that addition to the 4-position was preferable. Despite the highly different character of a ribose and a benzyl group, K-i values in the low nanomolar range were obtained for the benzyl-substituted derivatives. Compound 35, LUF5919, and compound 60, LUF5929, displayed the highest affinity (K-i = 39 nM for both compounds), having a polar surface area of 101 Angstrom(2) and 85 Angstrom(2), respectively.
