As of 2026-09-14

Adrenergic receptor alpha shows approved-linked disease relevance led by cardiovascular disease. 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 P35348. Start with cardiovascular disease, then reuse UniProt P35348 as the stable protein anchor across project notes and exports.

Adrenergic receptor alpha shows approved-linked disease relevance led by cardiovascular disease. 5 more disease programs remain visible in the same review block. 4 linked drugs remain visible in the same block.

Start review with cardiovascular disease because it currently carries approved-linked support. Linked drugs include ERGOLOID MESYLATES, MOXISYLYTE, PHENTOLAMINE MESYLATE, RAUWOLFIA SERPENTINA. This disease block keeps the Open Targets-ready contract explicit while current evidence comes from ChEMBL mechanism and indication mappings.
