(-)-Indolactam V 是 PKC 的激活劑，對 η-CRD2 (PKCη 代替肽)，γ-CRD2 (PKCγ 代替肽) 的 Ki 值分別為 3.36 nM 和 1.03 μM，對 PKC C1A 和 C1B 結(jié)構(gòu)域的 Kd 值分別為 5.5 nM (η-C1B)，7.7 nM (ε-C1B)，8.3 nM (δ-C1B)，18.9 nM (β-C1A-long)，20.8 nM (α-C1A-long)，137 nM (β-C1B)，138 nM (γ-C1A) 和 213 nM (γ-C1B)，具有抗腫瘤活性。
(-)-Indolactam V is a PKC activator, with K
i
s of 3.36 nM, 1.03 μM for η-CRD2 (PKCη surrogate peptide), γ-CRD2 (PKCγ surrogate peptide), and has antitumor activity. (-)-Indolactam V shows K
d
s of 5.5 nM (η-C1B), 7.7 nM (ε-C1B), 8.3 nM (δ-C1B), 18.9 nM (β-C1A-long), 20.8 nM (α-C1A-long), 137 nM (β-C1B), 138 nM (γ-C1A), 213 nM (γ-C1B), respectively. (-)-Indolactam V (20 nM-5 μM) dose-dependently affects multiple hESC lines, such as HUES 2, 4 and 8. (-)-Indolactam V also increases the mRNA levels of Pdx1, HNF6, PTF1A, SOX9, HB9 and PROX1. In addition, (-)-Indolactam V (300 nM) functions in both mouse and human cells and confirms that some signals for pancreatic development.
