Understanding YK11 SARM: Scientific Overview

Chemical Profile

YK11 (CAS: 1370003-76-1) is classified as a synthetic, steroidal selective androgen receptor modulator. Its chemical structure, (17α,20E)-17,20-[(1-Methoxyethylidene)bis(oxy)]-3-oxo-19-norpregna-4,20-diene-21-carboxylic acid methyl ester, features a steroidal backbone with specific modifications that contribute to its unique pharmacological profile in preclinical investigations.

Mechanism of Action (Reported in Research)

Laboratory research has identified several mechanisms of interest:

Androgen Receptor Interaction: Studies by Kanno et al. (2011) demonstrated that YK11 functions as a partial agonist at the androgen receptor. Unlike full agonists, YK11 does not induce the complete N/C interaction of the AR typically observed with endogenous androgens, suggesting a selective activity profile in cellular models.

Myogenic Pathway Effects: Research using C2C12 myoblast cultures has shown that YK11 influences the expression of follistatin, a protein that acts as an antagonist to myostatin—a negative regulator of muscle development. This follistatin-mediated pathway represents a mechanistically distinct feature compared to other compounds in its class (Kanno et al., 2013).

Osteoblast Activity: Preliminary findings using MC3T3-E1 osteoblast cells suggest potential modulation of markers associated with bone formation processes, though further research is needed to fully characterize these effects.

Areas of Research Interest

YK11 continues to be investigated in preclinical models across several research domains, including:

• Molecular mechanisms of selective androgen receptor modulation
• Regulation of myostatin/follistatin expression pathways
• Signaling cascades in myogenic differentiation
• Structure-activity relationships in steroidal SARMs
• Comparative analysis with non-steroidal SARMs
