Synthesis, in vitro, and in vivo (Zebra fish) antitubercular activity of 7,8-dihydroquinolin-5(6H)-ylidenehydrazinecarbothioamides

We, herein, describe the synthesis of a series of novel aryl tethered 7,8-dihydroquinolin-5(6H)-ylidenehydrazinecarbothioamides 4a-v, which showed in vitro and in vivo antimycobacterial activity against Mycobacterium tuberculosis (Mtb) H37Rv. The intermediates dihydro-6H-quinolin-5-ones 3a-v were synthesized from beta-enaminones, reacting with cyclochexane-1,3-dione/5,5-dimethylcyclohexane-1,3-dione and ammonium acetate using a modified Bohlmann-Rahtz reaction conditions. They were further reacted with thiosemicarbazide to give the respective hydrazine carbothioamides 4a-v. All the new analogues 4a-v, were characterized by their NMR and mass spectral data analysis. Among the twenty-two compounds screened for in vitro antimycobacterial activity against Mycobacterium tuberculosis H37Rv (ATCC27294), two compounds, 4e and 4j, exhibited the highest inhibition with an MIC of 0.39 mu g/mL. Compounds 4a, 4g, and 4k were found to inhibit Mtb at an MIC of 0.78 mu g/mL. Hydrazinecarbothioamides 4a-k, exhibited enhanced activity than dihydroquinolinones 3a-k. The observed increase in potency provides a clear evidence that hydrazinecarbothioamide is a potential pharmacophore, collectively imparting synergistic effect in enhancing antitubercular activity of the dihydroquinolinone core. The in vivo (Zebra fish) antimycobacterial screening of the in vitro active molecules led to the identification of a hit compound, 4j, with significant activity in the Mtb nutrient starvation model (2.2-fold reduction). Docking studies of 4j showed a hydrogen bond with the P156 residue of the protein.

High-performance liquid chromatographic enantioseparation of unusual secondary amino acids on a D-penicillamine-based chiral ligand exchange column

The application of a chiral ligand-exchange column (CLEC) for the direct high-performance liquid chromatographic enantioseparation of unusual secondary amino acids using D-penicillamine-Cu(II) complex as chiral selector is reported. The amino acids investigated were pyrrolidine-2-carboxylic acid, piperidine-2-carboxylic acid, piperazine-2-carboxylic acid, morpholine-3-carboxylic acid, and thiomorpholine-3-carboxylic acid analogs. Chromatographic results are given as the retention, separation, and resolution factors. The chromatographic conditions were varied to achieve optimal separation. The elution sequence of the enantiomers was determined and in most cases the S isomer eluted before R.

Future efforts will undeniably focus on the diversification of the new catalytic transformations. These may comprise an expansion of the substrate scope from aromatic and heteroaromatic compounds to other hydrocarbons. 830-09-1, you can contact me at any time and look forward to more communication.

Discovery of N-methylpiperazinyl flavones as a novel class of compounds with therapeutic potential against Alzheimer’s disease: synthesis, binding affinity towards amyloid beta oligomers (A beta o) and ability to disrupt A beta o-PrPC interactions

With no currently available disease-modifying drugs, Alzheimer’s disease is the most common type of dementia affecting over 47 million people worldwide. In light of the most recent discoveries placing the cellular prion protein (PrPC) as a key player in amyloid beta oligomer (A beta o)-induced neurodegeneration, we investigated whether the neuroprotective potential of nature-inspired flavonoids against A beta-promoted toxicity would translate into the ability to disrupt PrPC-A beta o interactions. Hence, we synthesized a small library of flavones and studied their binding affinity towards A beta o by STD-NMR. C-glucosyl flavones exhibited improved binding affinity with morpholine, thiomorpholine or N-methylpiperazine rings attached to the flavone skeleton in ring B para position. Moreover, a N-methylpiperazinyl flavone displayed suitable physico-chemical properties and optimal water solubility even without the sugar moiety, and a high interaction with A beta o involving the whole flavone core. Its C-glucosyl derivative, was, however, the best compound to inhibit PrPC-A beta o interactions in a dose-dependent manner, with 41 % of inhibition capacity at 10 mu M. The potential of C-glucosyl flavones and their aglycones as protein-protein interaction inhibitors able to tackle PrPC-A beta o interactions is here presented for the first time, and supports this class of compounds as new prototypes for further development in the treatment of Alzheimer’s disease.

Antihypertensive Properties of a Novel Morphologic Derivative (4-tert-buthyl-2,6-bis(thiomorpholine-4-ilmethyl)phenol)

We evaluated the antihypertensive properties of 4-tert-buthyl-2,6-bis(thiomorpholine-4-ilmethyl)phenol (TBTIF). Spontaneously hypertensive rats were treated with TBTIF or captopril (both at 1 mg center dot kg(-1)center dot d(-1) intramuscularly for 4 days), and their blood pressure (BP) was assessed. In some experiments, concentration response curves to angiotensin I or angiotensin II were generated in rat aortic rings and in the absence or presence of Ang-(1-7), N-G-monomethyl l-arginine, or both; additionally, the angiotensin-converting enzyme (ACE) and ACE2 mRNA levels were quantified in the aortic rings using reverse transcription-polymerase chain reaction. TBTIF diminished BP and reduced angiotensin I- or angiotensin II-induced vasoconstriction. The presence of Ang-(1-7) induced a greater reduction in vasoconstriction, and this effect was reversed by l-N-G-monomethyl arginine. Moreover, TBTIF decreased the mRNA of ACE and increased the mRNA of ACE2. In conclusion, TBTIF diminished rat BP through nitric oxide-dependent and nitric oxide-independent mechanisms. In contrast to captopril, TBTIF exhibits better antihypertensive properties through mechanisms that involve ACE2.

Identification of Advanced Reaction Products Originating from the Initial 4-Oxo-2-nonenal-cysteine Michael Adducts

4-Oxo-2-nonenal (ONE), an aldehyde originating from the peroxidation of omega 6 polyunsaturated fatty acids, preferentially reacts with the cysteine residues of protein. Despite the fact that there has been significant recent interest in the protein reactivity and biological activity of ONE, the structural basis of the ONE-cysteine adducts remain to be established. In the present study, to gain a structural insight into the sulfhydryl modification by ONE, we characterized reaction products that originated from the initial ONE-cysteine Michael adducts. N-Acetyl-L-cysteine (10 mM) was incubated with an equimolar concentration of ONE in 0.1 M phosphate buffer (pH 7.4) at 37 degrees C. Within I h of incubation, the reaction of N-acetyl-L-Cysteine with ONE resulted in the formation of two (C-2 and C-3) Michael addition products possessing a carbonyl functionality. Subsequent incubation of the reaction mixture resulted in their disappearance and concomitant formation of advanced reaction products, including a minor product III and major products IVa, IVb, and V. Product III was identified to be a thiomorpholine derivative, 4-acetyl-5-hydroxyl-6-(2-oxoheptyl)thiomorpholine-3-carboxylic acid, which might have originated from the C-2 Michael addition product. The major products were identified to be the novel 2-cyclopentenone derivatives, that is, 2-(acetylamino)-3-[(3-butyl-4-oxocyclopent-2-en-1-yl)sulfanyl] propionic acid (IVa and its isomer IVb) and 2-(acetylamino)-3-[(4-butyl-5-oxocyclopent-3-en-1-yl)sulfanyl]propionic acid (V), which might be generated through the base-catalyzed cyclization of the C-2 and C-3 Michael addition products, respectively. The furan derivative, which has been reported as the end product of the Michael adducts, was found to be formed only under acidic conditions. Thus, this study identified the novel ONE-cysteine adducts, including the most prominent 2-cyclopentenone derivatives, that originated from the initial Michael adducts.

Recommanded Product: 2-Methoxybenzoic acid, In conclusion, we affirm that quantitative kinetic descriptions of catalytic behavior continue to serve as an indispensable tool to navigate research efforts.you can also check out more blogs about 579-75-9.
