Review-ready Target Rationale

Why Histone deacetylase matters

As of 2026-09-13

Histone deacetylase is reviewed as Histone deacetylase 1 (UniProt Q13547); Histone deacetylase shows approved-linked disease relevance led by neoplasm. 5 more disease programs remain visible in the same review block.; 5 linked drugs keep this evidence frame grounded.; the current evidence base includes 10 approved drugs, 4392 compounds, and 1294 assays, with lead potency reaching pChEMBL 9.8.

Protein context

Histone deacetylase 1

Histone deacetylase 1 Sequence length is 482 aa.

Review this target as Histone deacetylase, mapped to UniProt Q13547. ChEMBL maps the protein component as Histone deacetylase 1. Sequence length is 482 aa.

Disease context

neoplasm

Histone deacetylase shows approved-linked disease relevance led by neoplasm. 5 more disease programs remain visible in the same review block. 5 linked drugs keep the rationale reviewable. 5 additional disease programs remain visible in the same card. Linked drugs include ABEXINOSTAT, BELINOSTAT, CUDC-101.

Start review with neoplasm because it currently carries approved-linked support. Linked drugs include ABEXINOSTAT, BELINOSTAT, CUDC-101, ENTINOSTAT. This disease block keeps the Open Targets-ready contract explicit while current evidence comes from ChEMBL mechanism and indication mappings.
