Novel anion receptors for selective recognition of dimethyl phosphinate and carboxylate

, p. 212 - 221 (2017)
We have designed and synthesized new anion receptors 1 and 2, which have amide N[sbnd]H, pyrrole N[sbnd]H and vinyl C[sbnd]H as hydrogen bond donors. These receptors are selective for dimethyl phosphinate and carboxylates. Due to electron withdrawing effect of the cyano group which is trans to the vinyl hydrogen with respect to carbon-carbon double bond, receptor 1 has higher binding constants for phosphinate and carboxylate than those of receptor 2. Modeling studies shows that cyano group polarized all three hydrogens through planar π-electron network. In addition, receptor 1 gave orange colored 1,4-addition product for cyanide.

A series of aryl phenoxy methyl triazole conjugated with thiosemicarbazides were designed, synthesized, and evaluated for their tyrosinase inhibitory activities in the presence of L-dopa and L-tyrosine as substrates. All the compounds showed tyrosinase inhibition in the sub-micromolar concentration. Among the derivatives, compound 9j bearing benzyl displayed exceptionally high potency against tyrosinase with IC50 value of 0.11 μM and 0.17 μM in the presence of L-tyrosine and L-dopa as substrates which is significantly lower than that of kojic acid as the positive control with an IC50 value of 9.28 μM for L-tyrosine and 9.30 μM for L-dopa. According to Lineweaver–Burk plot, 9j demonstrated an uncompetitive type of inhibition in the kinetic assay. Also, in vitro antioxidant activities determined by DPPH assay recorded an IC50 value of 68.43 μM for 9i. The melanin content of 9j was determined on B16F10 melanoma human cells which demonstrated a significant reduction of the melanin content. Moreover, the binding energies corresponding to the same ligand as well as computer-aided drug-likeness and pharmacokinetic studies were also carried out. Compound 9j also possessed metal chelation potential correlated to its high anti-TYR activity.

Anticonvulsants effective against multiple seizures are of wide interest as antiepileptic drugs, especially if active against pharmaco-resistant seizures. Herein, we synthesized 16 different, rationally designed 2-((6,7-dimethoxy-4-oxo-2-phenylquinazolin-3(4H)-yl)amino)-N-(substituted phenyl)acetamides and screened for anticonvulsant activities through in vivo experiments. Compound 4d emerged as prototype with excellent anti-seizure action in mice against electroshock, chemically induced and pharmaco-resistant 6-Hz seizure models with no symptoms of neurotoxicity and hepatotoxicity (ED50 = 23.5 mg/kg, MES, mice, i.p.; ED50 = 32.6 mg/kg, scPTZ, mice, i.p.; ED50 = 45.2 mg/kg, 6-Hz, mice, i.p.; TD50 = 325.9 mg/kg, mice, i.p.). In addition, investigation of compound 4l in mice for its pharmacological profile proved it as safer anticonvulsant, devoid of the side effects such as motor dysfunction and hepatotoxicity of classical antiepileptic drugs (ED50 = 26.1 mg/kg, MES, mice, i.p.; ED50 = 79.4 mg/kg, scPTZ, mice, i.p.; TD50 = 361.2 mg/kg, mice, i.p.). We also predicted physiochemical and pharmacokinetic properties of structurally optimized quinazolin-4(3H)-ones by a computational protocol. A combination of in vivo anticonvulsant profile, ex vivo toxicity, and in silico studies suggested that the synthesized compounds may be useful as broad-spectrum anti-seizure drug candidates with favorable pharmacokinetic parameters.

This study describes a virtual screening performed for two series of selenides (28 compounds), derived from N-phenylacetamides chlorides and 7-chloro-quinoline, to determine their potential for leishmanicidal activity against Leishmania amazonensis and Leishmania donovani. Seven compounds were predicted as potential leishmanicides; therefore, they were synthesized from elemental selenium, as a precursor for the production of NaHSe, and subsequent reactions with 4,7-dichloro-quinoline and N-phenylacetamides chlorides were performed. The compounds were characterized by infrared (IR), 1H and 13C nuclear magnetic resonance (NMR), and sent for in vitro cytotoxicity tests against L. amazonensis and were found to be active and selective, and two compounds presented half-maximal inhibitory concentrations (IC50) of 5.67 and 10.81 μg mL-1. They also presented good interaction energies in the docking study, suggesting that may exert their effects by inhibiting the N-myristoyltransferase and O-acetylserine sulfhydrylase enzymes in parasites.
