Isocryptotanshinone

고객리뷰

Based on 1 Customer Validation

Isocryptotanshinone is a dual STAT3 and PTP1B (IC₅₀ = 56.1 μM) inhibitor. Isocryptotanshinone inhibits STAT3 by binding to the STAT3 SH2 domain to block phosphorylation and nuclear translocation^[1][2]. Isocryptotanshinone exerts its anti-proliferative effect via the induction of cell cycle arrest, apoptosis, and pro-death autophagy, through the regulation of STAT3, AKT/mTOR and MAPK signaling pathways. Isocryptotanshinone suppresses the xenograft gastric cancer (GC) tumor growth in BALB/c nude mice. Isocryptotanshinone can be used for cancer research, such as lung cancer, breast cancer and GC.

Isocryptotanshinone (ICTS) (0-5 μM, 0-24 h) inhibits the constitutive STAT3 and p-STAT3 expression in A549 cells in a concentration- and time-dependent manner^[1].
Isocryptotanshinone (5 μM, 12 h) decreases STAT3 in the cytoplasm and p-STAT3 in nucleus in A549 cells^[1].
Isocryptotanshinone (5 μM, 0-4 h) inhibits the IL-6 (25 ng/mL)-stimulated expression of p-STAT3 in A549 cells in a time-dependent manner and almost completely abolishes p-STAT3 expression after 4 h^[1].
Isocryptotanshinone (0-10 μM, 0-24 h) attenuates the expression of survival-related proteins (Bcl-2, Bcl-xL, survivin, Mcl-1) in a time-dependent manner, and suppresses the expression of upstream regulators (EGFR and JAK2) in a concentration-dependent manner^[1].
Isocryptotanshinone (0-20 μM, 0-24 h) significantly inhibits the proliferation of A549 and 95D lung cancer cells in a concentration-dependent manner and induces apoptosis in A549 cells by remarkably increasing early apoptotic cell fractions, caspase 3/7 activity, and the expression of cleaved PARP^[1].
Isocryptotanshinone (0-10 μM, 0-24 h) induces pro-death autophagy in A549 cells by upregulating LC3II expression, promoting the accumulation of autophagic vacuoles and autolysosomes, and inhibiting the AKT/mTOR signaling pathway, similar to Cryptotanshinone (HY-N0174)^[1].
Isocryptotanshinone (0-20 μM, 24 h) inhibits proliferation (IC₅₀ = 12.5 μM) and colony formation in MCF-7 cells by inducing G1 phase cell cycle arrest and triggering early apoptosis^[3].
Isocryptotanshinone (2.5-10 μM, 0-24 h) triggers MAPK signaling activation in MCF-7 cells, which is characterized by the time- and concentration-dependent phosphorylation of JNK, ERK, and p38 MAPK^[3].
Isocryptotanshinone (0-40 μM, 0-72 h) suppressed the proliferation of GC cells, with IC₅₀ of 6.77 μM for SGC-7901 cells and 33.1 μM for MKN-45 cells^[4].
Isocryptotanshinone (0-40 μM, 24 h) induces G1/G0 phase cell cycle arrest and apoptosis in GC cells (SGC-7901 and MKN-45), an effect mediated through the inhibition of the STAT3 signaling pathway and the subsequent downregulation of cell cycle- and apoptosis-associated proteins (Cyclin D1, E2F1, Mcl-1, Bcl-2, survivin)^[4].

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
