YK11 is an investigational steroidal compound studied for its interactions with androgen receptor signaling and the follistatin–myostatin pathway. It has attracted research interest in skeletal muscle biology, myogenic differentiation, bone metabolism, and molecular mechanisms associated with muscle growth and tissue development.

Overview

YK11 is structurally distinct from many non-steroidal selective androgen receptor modulators and is investigated for its potential to influence androgen-responsive signaling. Preclinical research has examined its effects on androgen receptor activity and follistatin expression, providing a model for studying the relationship between androgen signaling and myostatin-related pathways.
