Specification

The Tenofovir disoproxil fumarate with the cas number 202138-50-9, is also called (1)(R)-5-((2-(6-Amino-9H-purin-9-yl)-1-methylethoxy)methyl)-2,4,6,8-tetraoxa-5-phosphanonanedioic acid, bis(1-methylethyl) ester, 5-oxide, (E)-2-butenedioate (1:1); (2)9-((R)-2-((Bis(((isopropoxycarbonyl)oxy)methoxy)phosphinyl)methoxy)propyl)adenine fumarate (1:1); (3)Bis(hydroxymethyl) (((R)-2-(6-amino-9H-purin-9-yl)-1-methylethoxy)methyl)phosphonate, bis(isopropyl carbonate)(ester), fumarate (1:1); (4) PMPA prodrug; (5) TDF; (6) Tenofovir DF; (7) Tenofovir disoproxil fumarate; (8) UNII-OTT9J7900I; (9) Viread.

The Tenofovir disoproxil fumarate has a brand name VIREAD. It is obtained from a fumaric acid salt of bis-isopropoxycarbonyloxymethyl ester derivative of tenofovir. Tenofovir disoproxil fumarate is converted to tenofovir, which is an acyclic nucleoside phosphonate (nucleotide) analog of adenosine 5'-monophosphate. Tenofovir exhibits activity against HIV-1 reverse transcriptase. VIREAD are taken orally . The most common aderse reactions include: light to moderate gastrointestinal upset (diarrhea, nausea, vomiting, and flatulence), Metabolic system of low incidence (1%) disease phosphatase, serum phosphate light to moderate decrease. It can also show dangerous lactic acidosis.

Physical properties of Tenofovir disoproxil fumarate are: (1)ACD/LogP: 2.037; (2)# of Rule of 5 Violations: 2; (3)ACD/LogD (pH 5.5): 2.01; (4)ACD/LogD (pH 7.4): 2.04; (5)ACD/BCF (pH 5.5): 19.53; (6)ACD/BCF (pH 7.4): 20.78; (7)ACD/KOC (pH 5.5): 286.95; (8)ACD/KOC (pH 7.4): 305.32; (9)#H bond acceptors: 15; (10)#H bond donors: 2; (11)#Freely Rotating Bonds: 17; (12)Flash Point: 342.5 °C; (13)Enthalpy of Vaporization: 94.85 kJ/mol; (14)Boiling Point: 642.7 °C at 760 mmHg; (15)Vapour Pressure: 2.06E-16 mmHg at 25°C
