Abstract
2-Azabicyclo[2.2.1]hept-5-en-3-one (Vince lactam) is known to be a valuable building block in synthetic organic chemistry and drug research. It is an important precursor to access of some blockbuster antiviral drugs such as Carbovir or Abacavir as well as other carbocyclic neuraminidase inhibitors as antiviral agents. The ring C=C bond of the Vince lactam allows versatile chemical manipulations to create not only functionalized γ-lactams, but also γ-amino acid derivatives with a cyclopentane framework. The aim of the current account is to summarize the chemistry of Vince lactam, its synthetic utility and application in organic and medicinal chemistry over the last decade.

Abstract
Novel γ-aminobutyric acid (GABA) analogues 3-5, having a bicyclo[3.1.0]hexene, [4.1.0]heptane, or [4.1.0]heptene backbone, respectively, were designed from the bioactive form analysis of the previous inhibitor 2 with a bicyclo[3.1.0]hexane backbone. Compounds 3-5 and 2 were synthesized from a common 1,7-diene intermediate 6 using ring-closing metathesis (RCM) to construct the key bicyclo backbones. Compounds 3-5 strongly inhibit betaine/GABA transporter 1 (BGT1) uptake, but compound 4 stands out with its selective low micromolar potency.

Abstract
Nucleic-acid-based small molecule and oligonucleotide therapies are attractive topics due to their potential for effective target of disease-related modules and specific control of disease gene expression. As the non-naturally occurring biomolecules, modified DNA/RNA nucleoside and oligonucleotide analogues composed of L-(deoxy)riboses, have been designed and applied as innovative therapeutics with superior plasma stability, weakened cytotoxicity, and inexistent immunogenicity. Although all the chiral centers in the backbone are mirror converted from the natural D-nucleic acids, L-nucleic acids are equipped with the same nucleobases (A, G, C and U or T), which are critical to maintain the programmability and form adaptable tertiary structures for target binding. The types of L-nucleic acid drugs are increasingly varied, from chemically modified nucleoside analogues that interact with pathogenic polymerases to nanoparticles containing hundreds of repeating L-nucleotides that circulate durably in vivo. This article mainly reviews three different aspects of L-nucleic acid therapies, including pharmacological L-nucleosides, Spiegelmers as specific target-binding aptamers, and L-nanostructures as effective drug-delivery devices.

Abstract
On the basis of the three-dimensional diversity-oriented conformational restriction strategy using key chiral cyclopropane units, we previously identified 3 ((2S,3R)-4-amino-3,4-methanobutyric acid) with a chiral trans-cyclopropane structure as a γ-aminobutyric acid (GABA) transporter inhibitor selective for GABA transporter (GAT) subtypes GAT-3 and BGT-1 (betaine/GABA transporter-1). Further conformational restriction of 3 with the rigid bicyclo[3.1.0]hexane backbone led to the successful development of the first highly potent and selective BGT-1 inhibitor 4 (IC50 = 0.59 μM). The bioactive conformation of 3 for BGT-1 was also identified.

Abstract
Most nucleosides in solution typically exist in equilibrium between two major sugar pucker forms, N-type and S-type, but bridged nucleosides can be locked into one of these conformations depending on their specific structure. While many groups have researched these bridged nucleosides for the purpose of determining their binding affinity for antisense applications, we opted to look into the potential for biological activity within these conformationally-locked structures. A small library of 2',4'- and 3',4'-bridged nucleoside analogues was synthesized, including a novel 3',4'-carbocyclic bridged system. The synthesized compounds were tested for antibacterial, antitumor, and antiviral activities, leading to the identification of nucleosides possessing such biological activities. To the best of our knowledge, these biologically active compounds represent the first example of 2',4'-bridged nucleosides to demonstrate such properties. The most potent compound, nucleoside 33, exhibited significant antiviral activity against pseudoviruses SF162 (IC(50)=7.0 μM) and HxB2 (IC(50)=2.4 μM). These findings render bridged nucleosides as credible leads for drug discovery in the anti-HIV area of research.

Abstract
Based upon the fact that L-nucleosides have been generally known to be less cytotoxic than D-counterparts, L-bicyclo[3.1.0]hexenyl carbanucleoside derivatives with a fixed north conformation were designed and synthesized by employing a novel synthetic strategy starting from (R)-epichlorohydrin in order to search for new anti-HIV agents with high potency and less cytotoxicity. A tandem alkylation, γ-lactonization, a chemoselective reduction of ester in the presence of γ-lactone functional group, a RCM reaction, and a Mitsunobu coupling reaction were used as key reactions. D-Counterpart nucleosides were also prepared according to the same synthetic method. Among the synthesized carbanucleosides, D-thymine nucleoside, D-2 and L-thymine nucleoside, L-2 exhibited excellent anti-HIV-1 and -2 activities, in MT-4 cells, which were higher than those of ddI, an anti-AIDS drug. Whereas D-2 exhibited high cytotoxicity in MT-4 cell lines, L-2 did not show any discernible cytotoxicity in all cell lines tested, reflecting that L-2 may be a good candidate for an anti-AIDS drug. L-2 also showed weak anti-HSV-2 activity without cytotoxicity. However, none of the synthesized nucleosides exhibited antiviral activities against RNA viruses including coxsakie, influenza, corona and polio viruses, maybe due to their 2',3'-dideoxy structure. Potent antiviral effects of D-2 and L-2 indicate that nucleosides belonging to a class of D4Ns can be an excellent candidate for anti-DNA virus agents. This research strongly supports L-nucleosides of a class of D4Ns to be a very promising candidate for antiviral agents due to its low cytotoxicity and a good antiviral activity.

Abstract
A series of bicylic 2'-deoxynucleosides that are locked in the N-type conformation due to three-carbon linkages between the 2'- and 4'-positions have been prepared by ring-closing diene or enyne metathesis. The alkene or 1,3-diene hereby introduced in the bicyclic system is further derivatized, the latter showing the expected potential for Diels-Alder reactions. Four derivatives that are saturated or unsaturated as well as functionalized at the 2'-4'-linkage are incorporated into oligodeoxynucleotides, and the affinity of these for complementary RNA and DNA is studied. Substantially increased affinity for complementary RNA is observed, especially with additional hydroxyl groups attached to the bicyclic system. On the other hand, decreased affinity for complementary single-stranded DNA is obtained, whereas only a very small influence on a triplex-forming oligonucleotide sequence is found. Hence, a strong RNA-selective nucleic acid recognition is seen, and it can be concluded that the 2'-oxygen atom is less important for the formation of DNA:RNA duplexes than for the formation of DNA:DNA duplexes. However, the lack of a 2'-oxygen in the duplex formation can be partly compensated by other hydrophilic moieties around the 2'-4'-linkages indicating structural water binding to be of significant importance.

Abstract
A concise synthetic route to a novel class of conformationally rigid 3',4'-cis-fused bicyclic nucleoside derivatives has been developed. The synthetic strategy and approach involves initial synthesis of a key [5,5]-bicyclic 6-aminofurofuran-2-one scaffold, employing an L-serine derived aminobutenolide as a strategically functionalized chiral template. Subsequent utilization of the carbonyl functionality of the above bicyclic lactone toward nucleobase incorporation, and linking of the resident amine functionality with appropriately protected amino acids completed the syntheses of the target bicyclic nucleoside-amino acid conjugates. Following the above route, and utilizing a combination of easily available nucleobases (4) and amino acids (4) as the two diversity elements, combinatorial synthesis of a 16-member demonstration library of the title amino acid-linked nucleosides has been accomplished.
