  Pyrrolidine-modified and 6-substituted analogs of nicotine: A structure—affinity investigation

  摘要：

  Because the structural requirements for the binding of nicotine to central nicotine receptors remain largely uninvestigated, we undertook a systematic investigation of pyrrolidine ring-opened analogs. This led to a subsequent investigation of related conformationally restricted derivatives of these analogs. The results are reported relative to the binding of several well-known and widely used nicotine receptor ligands. Although none of the ring-opened analogs binds with higher affinity than (-)nicotine (K-i = 2.3 nM), 3-(N-methyl-N-ethylaminomethyl)pyridine (12a; K-i = 28 nM) binds with significant affinity. A conformationally restricted analog of 12a, N-methyl [2,7]naphthyridine 30b (K-i = 18 nM), binds with similar affinity. 6-Substitution of 12a and racemic nicotine seems to be tolerated when the substituent is halogen or methyl. In functional studies (hypolocomotion and antinociception in mice; stimulus generalization in nicotine-trained rats) 30b retains nicotine-like properties. Several of the 6-substituted compounds were 2 to 20 times more potent than (+/-)nicotine. Although the intact pyrrolidine ring of nicotine appears important for optimal affinity, its pre presence is not an absolute requirement for activity, and 6-position substitution of the pyridine nucleus can influence both binding and functional activity.

  This invention relates to a novel class of heterocyclic compounds that bind chemokine receptors, inhibiting the binding of their natural ligands thereby. These compounds result in protective effects against infection by HIV through binding to chemokine receptors, including CXCR4 and CCR5, thus inhibiting the subsequent binding by these chemokines. The present invention provides a compound of Formula I wherein, W is a nitrogen atom and Y is absent or, W is a carbon atom and Y═H; R1 to R7 may be the same or different and are independently selected from hydrogen or straight, branched or cyclic C1-6 alkyl; R8 is a substituted heterocyclic group or a substituted aromatic group Ar is an aromatic or heteroaromatic ring each optionally substituted at single or multiple, non-linking positions with electron-donating or withdrawing groups; n and n′ are independently, 0-2; X is a group of the formula: Wherein, Ring A is an optionally substituted, saturated or unsaturated 5 or 6-membered ring, and P is an optionally substituted carbon atom, an optionally substituted nitrogen atom, sulfur or oxygen atom. Ring B is an optionally substituted 5 to 7-membered ring. Ring A and Ring B in the above formula can be connected to the group W from any position via the group V, wherein V is a chemical bond, a (CH2)n″ group (where n″=0-2) or a C═O group. Z is, (1) a hydrogen atom, (2) an optionally substituted C1-6 alkyl group, (3) a C0-6 alkyl group substituted with an optionally substituted aromatic or heterocyclic group, (4) an optionally substituted C0-6 alkylamino or C3-7 cycloalkylamino group, (5) an optionally substituted carbonyl group or sulfonyl.

  This invention describes various processes for synthesis and resolution of racemic amino-substituted fused bicyclic ring systems. One process utilizes selective hydrogenation of an amino-substituted fused bicyclic aromatic ring system. An alternative process prepares the racemic amino-substituted fused bicyclic ring system via nitrosation. In addition, the present invention describes the enzymatic resolution of a racemic mixture to produce the (R)- and (S)-forms of amino-substituted fused bicyclic rings as well as a racemization process to recycle the unpreferred enantioner. Further provided by this invention is an asymmetric synthesis of the (R)- or (S)-enantiomer of primary amino-substituted fused bicyclic ring systems.
