چکیده مقاله:

The present research article relates to the discovery of the novel drugs based on Zonisamide to treatment of autism disease. In first step, the electronic properties, reactivity and stability of the said compound are discussed. To attain these properties, the said molecular structure is optimized using B3LYP/6-311++G(d,p) level of theory at room temperature. The frontier molecular orbitals (FMOs) energies are used to calculate the global reactivity indices. Based on these indices, Zonisamide is a high stable compound and has low reactivity. In the next step, the optimized molecular structure of Zonisamide is docked into the potassium voltage-gated channel subfamily D member 2 (Kv4.2) and ligand-receptor interactions are analyzed. After that, the novel molecular structures based on Zonisamide backbone are designed and optimized. Designing the novel drugs are done using changes the backbone of Zonisamide and various functional groups. The interactions of the optimized molecular structures with the said potassium channel are analyzed using docking study.Based on these studies, ten molecules showed better ligand-receptor binding than Zonisamide. Finally, the physicochemical properties of the title compounds are analyzed. The compounds P3TZ, H2P3TZ, M2P3TZ, H4P3TZ and M4P3TZ are our novel drugs to treatment of autism disease based on the molecular docking and physicochemical properties.

The voltage-gated potassium channel subfamily KQT member 4 (KCNQ4) displays parallel evolution in echolocating bats.

Bats are the only mammals that use highly developed laryngeal echolocation, a sensory mechanism based on the ability to emit laryngeal sounds and interpret the returning echoes to identify objects. Although this capability allows bats to orientate and hunt in complete darkness, endowing them with great survival advantages, the genetic bases underlying the evolution of bat echolocation are still...

Voltage-gated potassium channel KCNV2 (Kv8.2) contributes to epilepsy susceptibility.

Mutations in voltage-gated ion channels are responsible for several types of epilepsy. Genetic epilepsies often exhibit variable severity in individuals with the same mutation, which may be due to variation in genetic modifiers. The Scn2a(Q54) transgenic mouse model has a sodium channel mutation and exhibits epilepsy with strain-dependent severity. We previously mapped modifier loci that influe...

Modeling the binding of three toxins to the voltage-gated potassium channel (Kv1.3).

The conduction properties of the voltage-gated potassium channel Kv1.3 and its modes of interaction with several polypeptide venoms are examined using Brownian dynamics simulations and molecular dynamics calculations. Employing an open-state homology model of Kv1.3, we first determine current-voltage and current-concentration curves and ascertain that simulated results accord with experimental ...

KCNA10: a novel ion channel functionally related to both voltage-gated potassium and CNG cation channels.

Our laboratory previously cloned a novel rabbit gene (Kcn1), expressed in kidney, heart, and aorta, and predicted to encode a protein with 58% amino acid identity with the K channel Shaker Kv1.3 (Yao X et al. Proc Natl Acad Sci USA 92: 11711-11715, 1995). Because Kcn1 did not express well (peak current in Xenopus laevis oocytes of 0.3 microA at +60 mV), the human homolog (KCNA10) was isolated, ...

A structural motif for the voltage-gated potassium channel pore.

Mutation studies have identified a region of the S5-S6 loop of voltage-gated K+ channels (P region) responsible for teraethylammonium (TEA) block and permeation/selectivity properties. We previously modeled a similar region of the Na+ channel as four beta-hairpins with the C strands from each of the domains forming the external vestibule and with charged residues at the beta-turns forming the s...
