AR-A014418 is a potent, selective and ATP-competitive GSK3β inhibitor with an IC50 of 104 nM。
Tofacitinib citrate is a JAK1/2/3 inhibitor with IC50s of 1, 20, and 112 nM, respectively.
HLY78 is an activator of the Wnt/β-catenin signaling pathway, which targets the DIX domain of Axin and potentiates the Axin-LRP6 association to promote Wnt signaling transduction[1].
AT7867 is a potent ATP-competitive inhibitor of Akt1/Akt2/Akt3 and p70S6K/PKA with IC50s of 32 nM/17 nM/47 nM and 85 nM/20 nM, respectively.
PF-5274857 is a potent and selective Smoothened (Smo) antagonist, inhibits Hedgehog (Hh) signaling with IC50 and Ki of 5.8 nM and 4.6 nM, respectively, and can penetrate the blood–brain barrier.IC50 value: 5.8 nMTarget: Smoothenedin vitro: PF-5274857 completely inhibits Shh-induced Hh pathway activity with IC50 of 2.7 nM measured by the transcriptional activity of Smo downstream gene Gli1 in MEF cells. The μ-opioid receptor is weakly inhibited by PF-5274857 with a dissociation constant of 36 μM subsequently determined in a functional assay [1].in vivo: PF-5274857 shows significant dose-dependent tumor growth inhibition (TGI) and induces tumor regression at high doses(>10 mg/kg)., PF-5274857 downregulates Gli1, Gli2, Ptch1, and Ptch2 gene expression levels to various degrees with maximal effects being achieved between 6 and 12 hours post-dose (Gli1 is the most sensitive gene), whereas PF-5274857 has little effect on Smo levels. In skin tissue, downregulation of Gli1 and Gli2 is also observed with a similar time course by PF-5274857. The model-derived drug concentration for half maximal inhibition of the tumor Gli1 mRNA production rate (IC50) by PF-5274857 is determined to be 8.9 nM in the Ptch+/?p53+/? medulloblastoma allograft mice, which mathematically corresponds to tumor regression of 119% TGI after 6 days of plasma exposure at this concentration. In the Ptch+/?p53?/? medulloblastoma allograft mice, the IC50 value is estimated to be 3.5 nM, consistent with the Ptch+/?p53+/? results. PF-5274857 is also able to cross the blood–brain barrier in rats within 4 hours post-dose [1].
Dynarrestin is a aminothiazole inhibitor of cytoplasmic dyneins 1 and 2. Dynarrestin rapidly and reversibly inhibits dynein 1-driven microtubule gliding in vitro plus a range of dynein 1- and 2-dependent processes in cells without affecting ATP hydrolysis and interfering with ciliogenesis. Dynarrestin suppresses hedgehog (Hh)-dependent proliferation of neuronal precursors and tumor cells[1].
ZINC00881524 is a ROCK inhibitor.
ALV1 is a potent Ikaros and Helios degrader. ALV1 potently reduces the protein abundance of IKZF1-4, CK1α (casein kinase 1α, CSNK1A1) and ribosomal protein RPL4. ALV1 shows similar degradation activity towards IKZF1/2/3. ALV1 induced Helios/CRBN dimerization. ALV1 promoted IL-2 secretion to a great extent[1].
Fasudil (HA-1077; AT877) hydrochloride semihydrate is a nonspecific RhoA/ROCK inhibitor and also has inhibitory effect on protein kinases, with an Ki of 0.33 μM for ROCK1, IC50s of 0.158 μM and 4.58 μM, 12.30 μM, 1.650 μM for ROCK2 and PKA, PKC, PKG, respectively. Fasudil hydrochloride semihydrate is also a potent Ca2+ channel antagonist and vasodilator[1][2][3].
Sp-cAMPS, a cAMP analog, is potent activator of cAMP-dependent PKA I 和 PKA II. Sp-cAMPS is also a potent, competitive phosphodiesterase (PDE3A) inhibitor with a Ki of 47.6 µM. Sp-cAMPS binds the PDE10 GAF domain with an EC50 of 40 μM[1][2][3].
