Description

Product Detail

Uses

21‑hydroxy‑17‑(1‑oxopropoxy)pregn‑4‑ene‑3,20‑dione is used as an intermediate in organic synthesis and pharmaceutical production.

Efficacy and Functions

Clascoterone is a novel androgen receptor inhibitor for the topical treatment of acne. It has demonstrated favorable efficacy and safety profiles with a low incidence of adverse events in clinical trials.

Biological Activity

Clascoterone (Winlevi, Cortexolone 17 alpha‑propionate, Cortexolone 17α‑propionate, CB‑03‑01) is a topical and peripherally selective antagonist of the androgen receptor (AR).

Mechanism of Action

As an androgen receptor inhibitor, clascoterone reduces sebaceous gland activity by blocking androgen receptors.

Synthesis

Starting from 17α,21‑dipropionate 102, a lipase‑catalyzed chemoselective alcoholysis reaction is carried out using lipase from Candida cylandracea with toluene as the solvent. Reaction conditions: n‑butanol is employed as the acyl acceptor. In this step, 17α,21‑dipropionate 102 is converted into clascoterone (XV) with a reaction yield of 99%.

Clascoterone (cortexolone 17α-propionate, CB-03-01) is a novel antagonist of androgen receptors. It binds to androgen receptors with high affinity. By competing with androgens for binding to androgen receptors, clascoterone works by blocking the androgen receptor signalling cascades that promote acne pathogenesis, such as sebaceous gland proliferation, excess sebum production, and inflammatory pathways. In August 2020, FDA approved clascoterone for the first-in-class topical treatment of acne (acne vulgaris) in male and female patients 12 years and older.
