Ac-YVAD-CHO (L 709049) is a selective and potent tetrapeptide interleukin 1β-converting enzyme (ICE) and caspase-1 (ICE)-like protease inhibitor with anti-inflammatory activity, inhibits cancer cell growth, and inhibits the production of mature IL-lβ. Ac-YVAD-CHO attenuates quinolinic acid-induced p53 increase and apoptosis in rat striatum.

Acth (1-4) is the ACTH N-terminal tetrapeptide.

Bilaid C is a tetrapeptide μ-opioid receptor agonist (Ki= 210 nM in HEK293 cell membranes expressing the human receptor) that has been found inPenicillium.1It inhibits forskolin-induced cAMP accumulation by 77% in HEK293 cells expressing the human μ-opioid receptor when used at a concentration of 10 μM. Bilaid C induces inward rectifying potassium channel (Kir) currents in rat locus coeruleus slices that endogenously express high levels of the μ-opioid receptor (EC50= 4.2 μM). 1.Dekan, Z., Sianati, S., Yousuf, A., et al.A tetrapeptide class of biased analgesics from an Australian fungus targets the μ-opioid receptorProc.

ND1-YL2 is a peptide-based PROTAC®Degrader of steroid receptor co-activator 1 (SRC-1; also known as nuclear receptor coactivator 1, NCOA1). ND1-YL2 is composed of a stapled peptide that binds SRC-1 (YL2) joined by a linker to a tetrapeptide that binds UBR box domains. Upon ternary complex formation, SRC-1 is polyubiquitinated and subsequently degraded via the N-degron pathway. This Degrader induces dose-dependent degradation of SRC-1 in the MDA-MB-231 triple negative breast cancer cell line (DC50 = 10 μM), and binds to the PAS-B domain of SRC-1 (Ki = 320 nM). ND1-YL2 inhibits MDA-MB-231 cell migrationin vitro, and suppresses metastasis of MDA-MB-231 cellsin vivo.
