An efficient preparation of 1,2-diamino-1-phenylheptane

A convenient four-step method for the preparation of the lipophilic vicinal diamine 1,2-diamino-1-phenylheptane is described. Condensation involving octan-2-one, benzaldehyde and ammonia is reported. Regioselective Schmidt rearrangement of 2,6-diphenyl-3-pentyl-piperidin-4-one (1) to 2,7-diphenyl-3-pentyl hexahydrodiazapin-5-one (3) is presented. Hydrolysis of 2,7-diphenyl-3-pentyl hexahydrodiazapin-5-one to 1,2-diamino-1-phenylheptane (4) is also reported for the first time.

Synthesis, spectral, stereochemical, single crystal XRD and biological studies of 3t-pentyl-2r,6c-diarylpiperidin-4-one picrate derivatives

Various substituted 3t-pentyl-2r,6c-diphenylpiperidin-4-one picrates (1-7) were synthesised and characterised by elemental analysis, FT-IR and NMR spectral studies. NMR spectral assignments were made unambiguously by their one dimensional (1H N

Synthesis, spectral, stereochemical and biological evaluation of (E)-2-(3-pentyl-2,6-diarylpiperidin-4-ylidene)-N-phenylhydrazinecarbothioamide derivatives

A series of new (E)-2-(3-pentyl-2,6-diarylpiperidin-4-ylidene)-N-phenylhydrazinecarbothioamides (1-6) were synthesized from the corresponding 3-pentyl-2,6-diarylpiperidine-4-ones condensation with phenyl thiosemicarbazide. Their chemical structures were confirmed by means of elemental analysis, FT-IR, 1H, and 13C NMR spectral techniques and for compound 3, HOMOCOSY, HSQC, HMBC, NOESY, and DEPT NMR spectral techniques. From the NMR spectral data the compounds (1-6) are shown to exist in normal chair conformation with equatorial orientation of all the phenyl groups at C-2 and C-6 and pentyl group at C-3. The synthesized compounds were screened for their bacterial activity against Pseudomonas aeruginosa, Staphylococcus aureus, Salmonella typhi, and Escherichia coli and fungal activity against Candida albicans, Rhizopus sp, Aspergillus niger, and Aspergillus flasvus.

Design, synthesis, molecular docking and antimicrobial evaluation of some tosyl carbamate derivatives

A series of tosyl carbamates have been synthesized and screened for their antibacterial and antifungal activities. All the synthesized compounds were characterized by spectral techniques (IR, 1H, 13C NMR and mass) and elemental analysis. in silico Molecular docking method was performed to study their antimicrobial activity against the target protein 1T9U. Compound 27 showed good antibacterial activity against Gram-positive and Gram-negative bacterial strains and compound 19 showed good antifungal activity. Molecular docking results revealed that the compound 19 exhibits minimum CDOCKER energy. Tosyl carbamate derivatives having good antimicrobial activities compared to that standard and all the synthesized compounds exhibits moderate CDOCKER scores.

Design, Synthesis, Characterization, Molecular docking, ADME Properties and In Vivo antipsychotic activity of aripiprazole related drugs candidates

Background: A series of newly synthesized compounds structurally related to Aripiprazole and Brexpiprazole, atypical antipsychotic and antidepressant used clinically for the treatment of schizophrenia, depression and bipolar disorder have been prepared and characterized by Elemental analysis, FT-IR, 1H NMR, 13C NMR, HSQC (2D NMR) and Mass spectrometry. All the compounds have been docked against, human A2A Adenosine receptor, human β2-Adrenergic G-Protein Coupled Receptor (GPCR) and ADME properties ware also evaluated. Objective: We focused on screening the neuroleptic activity of the synthesized drug molecules with different anti-psychotic animal models. Methods: All the drug molecules (10mg/kg) and also standard drug Aripiprazole (5mg/kg) were administered to their individual groups with 8 different animal models. Docking studies were carried out by Schrodinger 9.5 software to predict the antipsychotic activity and the pharmacokinetic properties were subjected to QIKPROP3.7 (Qikprop) module of Schr?dinger software to determine ADME property. Results: Both the receptor and ligand interaction shows an excellent dock score. ADME properties were also evaluated in the desirable range; finally these compounds have orally drug-likeness property. The results basically pointed out the fact that mutually the test molecules and control group may have the property to improve the positive symptoms of schizophrenia by reducing the dopamine levels of dopaminergic neurons of the brain. Conclusion: Docked against the protein to determine the Binding Energy, Glides core, Hydrogen bond, Total Intermolecular Energy and Interacting residues. ADME properties have been determined and obey the Lipinski's rule of five for drug likeness property. The synthesized compounds are used against Aripiprazole as a standard drug. The result has shown a promising effect in reducing the positive symptoms of psychosis in rats by sinking the dopamine levels in the frontal cortical region of the brain.

Synthesis, characterization, crystal structure, in-vitro antimicrobial evaluation and molecular docking studies of 1-(furan-2-carbonyl)-3-alkyl-2,6-diphenylpiperidin-4-one derivatives

A new class of various furoyl derivatives of 2,6-disubstituted piperidin-4-ones were synthesized and characterized by FTIR, NMR, mass and single crystal X-ray diffraction methods. The synthesized compounds were subjected to in-vitro antibacterial and antifungal activities against pathogenic microbial strains. The results pointed out that compounds 11, 12 & 14 displayed pronounced activity towards gram positive bacteria, whereas the compounds 9, 13 & 14 showed a superior inhibition activity against gram negative bacteria. The compound 9 showed a moderate activity towards the fungi. In addition, molecular docking experiments were also carried out.
