small molecule investigational

Deskripsi

Pradefovir mesilate (previously known as MB-06886, Hepavir B and remofovir mesylate) is an orally administered small molecule compound that belongs to a novel series of phosphate and phosphonate prodrugs of adefovir. Adefovir (Hepsera) is an acyclic phosphonate analogue of adenine that is used to treat hepatitis B virus. As adefovir is poorly absorbed and associated with a high level of nephrotoxicity, pradefovir mesilate was designed to specifically target the liver and reduce risks to external tissue, especially the kidneys, while improving results of adefovir.

Pradefovir is activated through oxidation that is mediated by cytochrome P-450 (CYP) 3A4, which is predominantly expressed in the liver. The novel prodrug is highly stable in both plasma and tissues and demonstrated potent preclinical and clinical anti-HBV activity. Pradefovir is undergoing phase II development for the treatment of chronic hepatitis B.

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.
