In Silico Appraisal, Synthesis, Antibacterial Screening and DNA Cleavage for 1,2,5-thiadiazole Derivative

Background: Thiadiazole not only acts as ?hydrogen binding domain? and ?two-electron donor system? but also as constrained pharmacophore. Methods: The maleate salt of 2-((2-hydroxy-3-((4-morpholino-1, 2,5-thiadiazol-3-yl) oxy) propyl) amino)- 2-methylpropan-1-ol (TML-Hydroxy)(4) has been synthesized. This methodology involves preparation of 4-morpholino-1, 2,5-thiadiazol-3-ol by hydroxylation of 4-(4-chloro-1, 2,5-thiadiazol-3-yl) morpholine followed by condensation with 2-(chloromethyl) oxirane to afford 4-(4-(oxiran-2-ylmethoxy)-1,2,5-thiadiazol- 3-yl) morpholine. Oxirane ring of this compound was opened by treating with 2-amino-2-methyl propan-1- ol to afford the target compound TML-Hydroxy. Structures of the synthesized compounds have been elucidated by NMR, MASS, FTIR spectroscopy. Results: The DSC study clearly showed that the compound 4-maleate salt is crystalline in nature. In vitro antibacterial inhibition and little potential for DNA cleavage of the compound 4 were explored. We extended our study to explore the inhibition mechanism by conducting molecular docking, ADMET and molecular dynamics analysis by using Schroedinger. The molecular docking for compound 4 showed better interactions with target 3IVX with docking score of -8.508 kcal/mol with respect to standard ciprofloxacin (docking score= -3.879 kcal/mol). TML-Hydroxy was obtained in silico as non-carcinogenic and non-AMES toxic with good percent human oral absorption profile (69.639%). TML-Hydroxy showed the moderate inhibition against Mycobacteria tuberculosis with MIC 25.00 mug/mL as well as moderate inhibition against S. aureus, Bacillus sps, K. Pneumoniae and E. coli species. Conclusion: In view of the importance of the 1,2,5-thiadiazole moiety involved, this study would pave the way for future development of more effective analogs for applications in medicinal field.

Directed synthesis of noncentrosymmetric molybdates using composition space analysis

A systematic investigation of the factors governing the reaction product composition, hydrogen bonding, and symmetry was conducted in the MoO 3/3-aminoquinuclidine/H2O system. Composition space analysis was performed through 36 individual reactions under mild hydrothermal conditions using racemic 3-aminoquinuclidine. Single crystals of three new compounds, [C7H16N2][Mo 3O10]¡¤H2O, [C7H 16N2]2[Mo8O26] ¡¤H2O, and [C7H16N2] 2[Mo8O26]¡¤4H2O, were grown. The relative phase stabilities for these products are dependent upon the reactant mole fractions in the initial reaction gel. This phase stability information was used to direct the synthesis of two new noncentrosymmetric compounds, using either (S)-(-)-3-aminoquinuclidine dihydrochloride or (R)-(+)-3-aminoquinuclidine dihydrochloride. [(R)-C7H 16N2]2-[Mo8O26] and [(S)-C7H16N2]2[Mo8O 26] both crystallize in the noncentrosymmetric space group P2 1 (No. 4), which has the polar crystal class 2 (C2). The second-harmonic generation activities were measured on sieved powders. The structure-directing properties of the molybdate components in each compound were determined using bond valence sums. The structures of all five compounds were determined using single-crystal X-ray diffraction.

Design, synthesis, and neurochemical evaluation of 5-(3-alkyl-1,2,4- oxadiazol-5-yl)-1,4,5,6-tetrahydropyrimidines as M1 muscarinic receptor agonists

A series of 5-(3-alkyl-1,2,4-oxadiazol-5-yl)-1,4,5,6- tetrahydropyrimidines (7a-h) was synthesized for biological evaluation as selective agonists for M1 receptors coupled to phosphoinositide (PI) metabolism in the central nervous system. Each ligand bound with high affinity to muscarinic receptors from rat brain as measured by inhibition of [3H]-(R)-quinuclidinyl benzilate ([3H]-(R)-QNB) binding. 5-(3-Methyl- 1,2,4-oxadiazol-5-yl)-1,4,5,6-tetrahydropyrimidine trifluoroacetate (CDD- 0098-J; 7a) displayed high affinity (IC50 = 2.7 ¡À 0.69 muM) and efficacy at muscarinic receptors coupled to PI metabolism in the rat cortex and hippocampus. Increasing the length of the alkyl substituent increased affinity for muscarinic receptors yet decreased activity in PI turnover assays. The hippocampal PI response of 7a was blocked by lower concentrations of pirenzepine (8) or by higher concentrations of either AF-DX 116 (9) or p- fluorohexahydrosiladifenidol (10), suggesting that at low concentrations 7a selectively stimulates PI turnover through M1 receptors.
