Abstract
COA-Cl is a newly synthesized adenosine analogue that exhibits various physiological activities. Its angiogenic, neurotropic, and neuroprotective potencies make it promising for the development of medicines. In this study, we show Raman spectroscopic study of COA-Cl to elucidate molecular vibrations and related chemical properties. Density functional theory calculations were combined with the Raman spectroscopic data to understand the details of each vibrational mode. Comparative analysis with adenine, adenosine, and other nucleic acid analogues enabled identification of unique Raman peaks originating from the cyclobutane moiety and chloro group of COA-Cl. This study provides fundamental knowledge and crucial insights for further development of COA-Cl and related chemical species.

Abstract
Oxetanocin A (Oxt-A), a novel oxetanosyl N-glycoside nucleoside, was isolated from Bacillus megaterium in 1986. It carries an oxetane ring on the sugar moiety of the nucleoside scaffold, which contributes to differences in its structure from those of common tetrahydrofuranyl-based nucleosides. In view of the unique 3D-spatial framework, the complete synthesis of Oxt-A has been achieved by multiple research groups. The pharmacological properties of this natural product have also been broadly investigated by pharmacists and chemists since its discovery. Notably, the potential antiviral effect of Oxt-A has captured attention of researchers in the field of antiviral agent development. Furthermore, epidemic outbreaks caused by viruses have been stimulating the preparation and modification of various Oxt-A analogs over the past few decades. However, none of the studies have overviewed the antiviral efficacies of this naturally occurring scaffold yet. Thus, the present review summarizes the synthesis, structural modification, and antiviral activities of Oxt-A and its derivatives. We believe that these comprehensive descriptions will provide a novel perspective for the discovery of antivirus drugs with well-improved performance and pave newer paths for combating sudden public health issues triggered by viruses in the future.

Abstract
Six novel carbocyclic oxetanocin A analogs (2-chloro-C.OXT-A; COA-Cl) with various hydroxymethylated or spiro-conjugated cyclobutane rings at the N(9)-position of the 2-chloropurine moiety were synthesized and evaluated using human umbilical vein endothelial cells. All prepared compounds (2a-f) showed good to moderate activity with angiogenic potency. Among these compounds, 100 µM cis-trans-2',3'-bis(hydroxymethyl)cyclobutyl derivative (2b), trans-3'-hydroxymethylcyclobutyl analog (2d), and 3',3'-bis(hydroxymethyl)cyclobutyl derivative (2e) had greater angiogenic activity, with relative tube areas of 3.43±0.44, 3.32±0.53, and 3.59±0.83 (mean±standard deviation (S.D.)), respectively, which was comparable to COA-Cl (3.91±0.78). These data may be important for further development of this class of compounds as potential tube formation agents.

Abstract
This review describes the synthesis and evaluation of novel nucleic acid derivatives performed by our research group to date. We developed a new method for the synthesis of 2-alkoxyadenosine analogs via nonaqueous diazotization-dediazoniation reactions. By applying these reactions, we effectively synthesized four types of carbocyclic oxetanocin analogs (2-alkoxy-C.OXT-A). The angiogenic activities of these compounds were evaluated using human umbilical vein endothelial cells. This resulted in increased activities of the analogs, especially of 2-methoxy-C.OXT-A and 2-isopropoxy-C.OXT-A, at a concentration of 100 μM; they showed angiogenic potency similar to or greater than that of vascular endothelial growth factor. We also synthesized and evaluated a novel series of uracil derivatives carrying a 3,5-dimethylbenzyl group at the N(3)-position and acting as non-nucleoside HIV-1 reverse transcriptase inhibitors. Some of these compounds showed good-to-moderate inhibitory activity, with EC₅₀ values in the submicromolar range. Among them, the analog 6-amino-1-(4-picolyl)-uracil showed significant HIV-1 reverse transcriptase inhibition, with an EC₅₀ value of 0.03 μM and a high selectivity index of 2863.
