Synthesis and biological evaluation of dihydroquinoline carboxamide derivatives as anti-tubercular agents

Sodium trifluoromethanesulfonate, and glacial acetic acid selectively catalyzed the synthesis of dihydroquinoline via Friedlaender annulation. The synthesized dihydroquinoline analogues coupled with different amines by the use of coupling reagent gave dihydroquinoline carboxamide derivatives in moderate to good yields. All the synthesized novel compounds were evaluated for the anti-tubercular activity and cytotoxic activities in vitro. Among tested 30 compounds, two compounds, 8g and 8h showed MIC value of 0.39 and 0.78 mug/mL, respectively against Mycobacterium tuberculosis H37Rv and they were found to be non-toxic. Also these two compounds exhibited good pharmacological properties and oral absorption when studied using in-silico models.

Facile conversion of para-benzoquinones to para-alkoxyphenols with primary/secondary alcohols and amberlyst-15: A process showing novel reducing property of such alcohols

A new efficient methodology has been developed for the synthesis of para-alkoxyphenols, an important group of anti-melanoma compounds, by heating alcoholic solutions of para-benzoquinones in the presence of amberlyst-15. The most notable feature here is the behaviour of the used primary or secondary alcohol as an effective reducing agent.

Effect of a-ring modifications on the DNA-binding behavior and cytotoxicity of pyrrolo[2,1-c][1,4]benzodiazepines

Several A-ring-modified analogues of the DNA-binding antitumor agent DC- 81 (5) have been synthesized in order to study structure- reactivity/cytotoxicity relationships. For two molecules (23 and 30) the modifications required the addition of a fourth ring to give the novel dioxolo[4,5-h]- and dioxano[5,6-h]pyrrolo[2,1-c][1,4]benzodiazepin-11-one (PBD) ring systems, respectively. Another three analogues (34, 38, and 48) have the native benzenoid A-ring replaced with pyridine, diazine, or pyrimidine rings to give the novel pyrrolo[2,1-c][1,4]pyridodiazepine, pyrrolo[2,1-c][1,4]diazinodiazepine, and pyrrolo[2,1- c][1,4]pyrimidinodiazepine systems, respectively. The other new analogues (16a,b) have extended chains at the C8-position of the DC-81 structure. During the synthesis of these compounds, a novel tin-mediated regiospecific cleavage reaction of the dioxole intermediate 18 was discovered, leading to the previously unknown iso-DC-81 (20). In addition, an unusual simultaneous nitration-oxidation reaction of 4-(3-hydroxypropoxy)-3-methoxybenzoic acid (8) was found to produce 3-(4-carboxy-2-methoxy-5-nitrophenoxy)propanoic acid (9), a key intermediate, in high yield. In general, the results of cytotoxicity and DNA-binding studies indicated that none of the changes made to the A-ring of the PBD system significantly improved either binding affinity or cytotoxicity in comparison to DC-81. This result suggests that the superior potency of natural products such as anthramycin (1), tomaymycin (2), and sibiromycin (3) is due entirely to differences in C-ring structure, and in particular exo or endo unsaturation at the C2-position and C2- substituents containing unsaturation. This study also provided information regarding the influence of A-ring substitution pattern on the relative stability of the interconvertible N10-C11 carbinolamine, carbinolamine methyl ether, and imine forms of PBDs.

Iron(III)-Catalyzed Arylation of Spiro-Epoxyoxindoles with Phenols/Naphthols towards the Synthesis of Spirocyclic Oxindoles

An efficient and highly regioselective iron(III)-catalyzed Friedel?Crafts-type arylation of spiro-epoxyoxindoles with phenols was developed for rapid access to 3-(3-indolyl)-oxindole-3-methanols, which could be further elaborated into benzofuranyl-spirooxindoles under Mitsunobu conditions. When spiro-epoxyoxindoles were reacted with naphthols in the presence of a catalytic amount of FeCl3?6 H2O in dichloromethane, they underwent a tandem Friedel?Crafts-type arylation and O-cyclization to yield novel naphthofuranyl-spirooxindoles in excellent yields. This method is applied to enable the efficient and highly regioselective synthesis of a small-molecule inhibitor of the sodium channel Nav1.7 (¡À)-XEN402, which is currently in a phase IIb clinical trial for the treatment of pain.

Understanding the binding of quinoline amines with human serum albumin by spectroscopic and induced fit docking methods

Seven new quinoline-based bioorganic compounds were prepared by solvent-free synthesis and characterized using spectral techniques. The binding of these compounds with human serum albumin (HSA) was investigated by multi-spectroscopic methods. The quenching of Trp fluorescence upon addition of these compounds to HSA confirmed their significant binding. The quenching analysis at three different temperatures revealed that the complex formation is static and the reaction is entropy driven, spontaneous, and exothermic. Hydrogen bonds and van der Waals forces mainly contributed in the interactions as confirmed by the negative DeltaH and DeltaS values as well as molecular docking. The results from the circular dichroism (CD) spectroscopy indicated the minimal conformational changes of the protein upon binding with these quinoline compounds. The specific binding site and mode of interactions with HSA were also modeled using induced fit molecular docking procedure and their binding site was found to be in the interface of domains II and III, which is similar to the binding of the drug iodipamide with serum albumin.

Synthesis of 4-azo-butenolides

An efficient, catalyst-free, microwave-assisted approach has been developed for the synthesis of 4-azo-butyenolides derivatives by condensing tetronic acid with various anilines. This approach exhibited good functional group compatibility and produced the desired products in good to excellent yields in just 30?40 min. This approach can be seen as a better alternative to protocols with long reaction times used for the synthesis of these compounds, which are synthons for the obtaining of quinolines.
