Tyroserleutide hydrochloride, isolated from the degradation products of porcine spleen[1], is a small molecular tripeptide which inhibits tumor growth both in vitro and in vivo[2].

IC50 Target

Antitumor tripeptide[1][2]

体外研究
(In Vitro)

Tyroserleutide (YSL) exhibits immuno-modulating effects, such as enhancing concanavalin (ConA) induced proliferation of mouse spleen lymphocytes, phagocytosis of mouse peritoneal macrophages, and the activity of natural killer (NK) cells[1].
Tyroserleutide (YSL), an immunologically therapeutic tripeptide, can promote hepatocarcinoma cell (H22) apoptosis through downregulating Bcl-2 and cyclin D1 expression[2].
Tyroserleutide is an ideal choice for inducing apoptosis of liver tumor cells[2].
Tyroserleutide inhibits tumor growth and does not cause severe toxicities in the major organs. Tyroserleutide can inhibit tumor cell migration[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

体内研究
(In Vivo)

Tyroserleutide (10-80 μg/kg; injection (i.p.) one time every day until mice are dead) displays obvious anti-tumor activity. Tyroserleutide significantly prolongs the survival time of the murine H22 implanted mice[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Female Kun-Ming mice (18-22 g, 6 week old) with H22 tumor model[1]
Dosage: 10, 20, 40, and 80 μg/kg
Administration: Injection (i.p.) one time every day until mice were dead.
Result: Survival times are 25.53±14.14, 25.82±14.29, 30.47±17.89, 35.06±20.90 days for 10, 20, 40, and 80 μg/kg, respectively.
