生物活性

Pam3CSK4 TFA is a toll-like receptor 1/2 (TLR1/2) agonist with an EC50 of 0.47 ng/mL for human TLR1/2[1].

体外研究
(In Vitro)

Pam3CSK4 is a TLR1/2 heterodimer recognises triacylated lipopeptides[1].
Pam3CSK4 (1 μg/mL) enhances the antibacterial functions of granulocyte macrophage-colony stimulating factor (GM-CSF) induced neutrophils to Methicillin-resistant Staphylococcus aureus (MRSA)[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
体内研究
(In Vivo)

Pam3CSK4 (5 mg/kg; i.p.; once a day for 9 days) alters brain, spleen and liver weights in neonatal mice[3].

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

Animal Model: Time-mated pregnant C57BL/6 wild-type mice; B6.129-Tlr2tm1Kir/J (TLR2 -deficient) mice[3]
Dosage: 5 mg/kg
Administration: Intraperitoneally (i.p.); once a day for 9 days
Result: After repeated administration from postnatal day (PND3) to PND11, brain weight was decreased compared with endotoxin-free saline-treated animals at PND12. Decreased volume of cerebral gray matter, white matter in the forebrain and cerebellar molecular layer that was accompanied by an increase in spleen and liver weight at PND12.
