Arbaclofen

DB08891

small molecule investigational

Deskripsi

Arbaclofen, or STX209, is the R-enantiomer of baclofen. It is believed to be a selective gamma-amino butyric acid type B receptor agonist, and has been investigated as a treatment for autism spectrum disorder and fragile X syndrome in randomized, double blind, placebo controlled trials. It has also been investigated as a treatment for spasticity due to multiple sclerosis and spinal cord injury. Arbaclofen was investigated as a treatment for gastroesophageal reflux disease (GERD); however, with disappointing results.

1. Pendahuluan & Konsep

Fitur visualisasi ini dikembangkan menggunakan pendekatan Graph Theory untuk memetakan hubungan polifarmasi dan molekuler. Entitas (Obat, Target, Gen) direpresentasikan sebagai Simpul (Nodes), sedangkan hubungan biologisnya sebagai Sisi (Edges).

2. Sumber Data (Validasi)

Data Obat: Diekstraksi dari elemen drugbank-id dan name pada skema XML DrugBank.
Target Protein: Diambil dari elemen targets/target yang memuat polipeptida sasaran.
Genetik: Disinkronisasi dari sub-elemen gene-name dan varian snp-effects.
Genetik: Jumlah titik node dibatasi pada maksimal 10 (Slice=10) interaksi untuk menghindari tumpukan data.

3. Algoritma Visualisasi

Tata letak grafik menggunakan algoritma Force-Directed Graph (Barnes-Hut). Model fisika ini menerapkan gaya tolak-menolak antar simpul (Gravitasi: -3000) agar tidak tumpang tindih, serta gaya pegas (Spring: 0.04) pada garis penghubung untuk fleksibilitas interaksi.

Profil Farmakokinetik

Waktu Paruh (Half-Life) -

Volume Distribusi -

Klirens (Clearance) Blood clearance of an IV bolus of R-baclofen in rats, monkeys, and dogs, resulted in a half life of 1.6-3.4hours, in one study. Total blood clearance was reported to be 0.51±0.13L/h/kg in rats, 0.31±0.11L/h/kg in monkeys, and 0.24±0.01L/h/kg in dogs. (2)

Absorpsi

Unlike baclofen, absorption of arbaclofen is not limited to the upper small intestine. Arbaclofen can also be absorbed in the lower small intestine and the colon, allowing for the development of sustained release formulations.

Metabolisme

Data metabolisme tidak tersedia.

Rute Eliminasi

>80% of R-baclofen is renally eliminated unchanged.
