As of 2026-09-13

Trifunctional purine biosynthetic protein adenosine-3 shows approved-linked disease relevance led by mesothelioma. 5 more disease programs remain visible in the same review block. 4 linked drugs keep the current disease frame grounded. Protein identity stays anchored to UniProt P22102. Start with mesothelioma, then reuse UniProt P22102 as the stable protein anchor across project notes and exports.

mesothelioma

Trifunctional purine biosynthetic protein adenosine-3 shows approved-linked disease relevance led by mesothelioma. 5 more disease programs remain visible in the same review block. 4 linked drugs remain visible in the same block.

Start review with mesothelioma because it currently carries approved-linked support. Linked drugs include PEMETREXED, PEMETREXED DISODIUM, PEMETREXED MONOHYDRATE, PEMETREXED TROMETHAMINE. This disease block keeps the Open Targets-ready contract explicit while current evidence comes from ChEMBL mechanism and indication mappings.
