tenofovir alafenamide

CHEBI:90926 ·resolve ·ANTIVIRAL ·EXACT SEEDED

An L-alanine derivative that is isopropyl L-alaninate in which one of the amino hydrogens is replaced by an (S)-({[(2R)-1-(6-amino-9H-purin-9-yl)propan-2-yl]oxy}methyl)(phenoxy)phosphoryl group. A prodrug for tenofovir, it is used (as the fumarate salt) in combination therapy for the treatment of HIV-1 infection. — ChEBI

Drug registries

Identifiers that name a drug rather than a structure. One of these can cover a parent compound, its salts and its stereoisomers, which this corpus keeps as separate records, so it is not an equivalence of structure.

Patents and articles

Documents about this compound. A patent covers a class and an article covers a topic; neither identifies a structure.
