METHODS AND COMPOSITIONS COMPRISING DIAMINES AS NEW ANTI-TUBERCULAR THERAPEUTICS

Methods and compositions for treating disease caused by infectious agents, particularly tuberculosis. In particular, methods and compositions comprising novel diamine compositions for the treatment of infectious diseases are provided. In one embodiment, these methods and compositions are used for the treatment of mycobacterial infections, including, but not limited to, tuberculosis.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.123536-14-1, you can also check out more blogs about123536-14-1

Copper-Catalyzed Carboxylation of C-F Bonds with CO2

An effective Cu-catalyzed selective formal carboxylation of C-F bonds with an atmospheric pressure of CO2 is reported. A variety of gem-difluoroalkenes, gem-difluorodienes, and alpha-trifluoro-methyl alkenes show high reactivity and selectivity for this ipso monocarboxylation. Under mild conditions, diverse important alpha-fluoroacrylic acids and alpha,alpha-difluorocarboxylates are obtained in good-to-high yields. Moreover, this operationally simple protocol features good functional group tolerance, is readily scalable, and the resulting products are readily converted into bioactive alpha-fluorinated carbonyl compounds, indicating potential application in biochemistry and drug discovery. Mechanistic studies reveal that fluorinated boronate esters might be vital intermediates in this transformation.

Synthesis of quinazoline-2,4-dione and naphthalimide derivatives as new 5-HT3 receptor antagonists

New potent 5-HT3 receptor antagonists have been designed from the naphthalimide moiety and a quinuclidine heterocycle and the structure-activity relationships are discussed here on the basis of the nature of the substituent on the aromatic system. The biological activity of the compounds was evaluated in binding assays with [3H]BRL-43694 and by inhibition of the Bezold-Jarisch reflex. Compound 22 with a 4-amino substituent was equipotent to the reference compounds. In contrast to the benzamide derivatives, the activity resides essentially in the (R) enantiomer (K(i) = 0.15 ¡À 0.05 nM, ID50 = 1.6 mug/kg/iv) and it is demonstrated that the additional carbonyl group is involved in the inversion of the enantioselectivity of the receptor. Conformational studies of (R)-22 demonstrated the presence of a locked structure with 4 minimal energy conformers which were compared to those of (S)-zacopride. The superimposition of the putative active conformers emphasized the presence of a second polar group in the binding site. The fluorescent properties of the compounds were studied and indicate that (R)-22 and its derivatives may be promising tools for the direct visualization of 5-HT3 receptors.

Discovery and structure-activity relationship of quinuclidine benzamides as agonists of alpha7 nicotinic acetylcholine receptors

A library of benzamides was tested for alpha7 nicotinic acetylcholine receptor (nAChR) agonist activity using a chimeric receptor in a functional, cell-based, high-throughput assay. From this library, quinuclidine benzamides were found to have alpha7 nAChR agonist activity. The SAR diverged from the activity of this compound class verses the 5-HT3 receptor, a structural homologue of the alpha7 nAChR. PNU-282987, the most potent compound from this series, was also shown to open native alpha7 nAChRs in cultured rat neurons and to reverse an amphetamine-induced gating deficit in rats.

Intriguing case of Pseudo-isomorphism between chiral and racemic crystals of rac- and (S)/(R)2-(1,8-Naphthalimido)-2-quinuclidin-3-yl, and their reactivity toward I2 and IBr

Condensation reactions between 1,8-naphthalic anhydride and racemic 3-aminoquinuclidine or chiral (S) or (R)-(-)-3-aminoquinuclidine allowed preparation of three novel racemic and enantiopure aza-donor ligands, namely NMiABCO (1), (S)NMiABCO (2a), and (R)NMiABCO (2b). Racemic NMiABCO (1) crystallizes in the monoclinic space group P21/c, Z? = 1, while enantiopure (S)NMiABCO (2a) and (R)NMiABCO (2b) crystallize in the chiral monoclinic space group P21, Z? = 2, and show significant pseudocentrosymmetry, being pseudo-isomorphous with racemic NMiABCO (1). Reactivity of both racemic and enantiopure NMiABCO toward iodine and interhalogen IBr was also investigated as a way to remove the pseudoisomorphism, yielding the three new molecular adducts [NMiABCO¡¤I2] (3), [(S)NMiABCO¡¤I2]¡¤xCHCl3 (4), [(S)NMiABCO¡¤IBr]¡¤xCHCl3 (5) and the molecular salt [HNMiABCO][IBr2] (6). Synthesis of complexes 3 and 4 was also carried out in the solid state via kneading and vapor digestion techniques. All compounds were fully characterized via single crystal and powder X-ray diffraction and Raman spectroscopy.

Pharmacological profile of zacopride and new quaternarized fluorobenzamide analogues on mammalian alpha7 nicotinic acetylcholine receptor

Abstract From quaternarization of quinuclidine enantiomers of 2-fluoro benzamide LMA10203 in dichloromethane, the corresponding N-chloromethyl derivatives LMA10227 and LMA10228 were obtained. Here, we compared the agonist action of known zacopride and its 2-fluoro benzamide analogues, LMA10203, LMA10227 and LMA10228 against mammalian homomeric alpha7 nicotinic acetylcholine receptor expressed in Xenopus oocytes. We found that LMA10203 was a partial agonist of alpha7 receptor with a pEC50 value of 4.25 ¡À 0.06 muM whereas LMA10227 and LMA10228 were poorly active on alpha7 homomeric nicotinic receptor. LMA10227 and LMA10228 were identified as antagonists of acetylcholine-induced currents with IC50 values of 28.4 muM and 39.3 muM whereas LMA10203 and zacopride possessed IC50 values of 8.07 muM and 7.04 muM, respectively. Moreover, despite their IC50 values, LMA10227 was the most potent inhibitor of nicotine-induced current amplitudes (65.7 ¡À 2.1% inhibition). LMA10203 and LMA10228 had the same inhibitory effects (26.5 ¡À 7.5% and 33.2 ¡À 4.1%, respectively), whereas zacopride had no significant inhibitory effect (4.37 ¡À 4%) on nicotine-induced responses. Our results revealed different pharmacological properties between the four compounds on acetylcholine and nicotine currents. The mode of action of benzamide compounds may need to be reinterpreted with respect to the potential role of alpha7 receptor.

Varying Chirality Across Nicotinic Acetylcholine Receptor Subtypes: Selective Binding of Quinuclidine Triazole Compounds

The novel quinuclidine anti-1,2,3-triazole derivatives T1-T6 were designed based on the structure of QND8. The binding studies revealed that the stereochemistry at the C3 position of the quinuclidine scaffold plays an important role in the nAChR subtype selectivity. Whereas the (R)-enantiomers are selective to alpha7 over alpha4beta2 (by factors of 44-225) and to a smaller degree over alpha3beta4 (3-33), their (S)-counterparts prefer alpha3beta4 over alpha4beta2 (62-237) as well as over alpha7 (5-294). The (R)-derivatives were highly selective to alpha7 over alpha3beta4 subtypes compared to (RS)- and (R)-QND8. The (S)-enantiomers are 5-10 times more selective to alpha4beta2 than their (R) forms. The overall strongest affinity is observed for the (S)-enantiomer binding to alpha3beta4 (Ki, 2.25-19.5 nM) followed by their (R)-counterpart binding to alpha7 (Ki, 22.5-117 nM), with a significantly weaker (S)-enantiomer binding to alpha4beta2 (Ki, 414-1980 nM) still above the very weak respective (R)-analogue affinity (Ki, 5059-10436 nM).
