Field of application
BO-264 is a highly potent and orally active transforming acidic coiled-coil 3 (TACC3) inhibitor with an IC50 of 188 nM and a Kd of 1.5 nM. BO-264 specifically blocks the function of FGFR3-TACC3 fusion protein. BO-264 induces spindle assembly checkpoint (SAC)-dependent mitotic arrest, DNA damage and apoptosis. BO-264 has broad-spectrum antitumor activity[1].

Description: BO-264 is a highly potent and orally active transforming acidic coiled-coil 3 (TACC3) inhibitor with an IC50 of 188 nM and a Kd of 1.5 nM. BO-264 specifically blocks the function of FGFR3-TACC3 fusion protein. BO-264 induces spindle assembly checkpoint (SAC)-dependent mitotic arrest, DNA damage and apoptosis. BO-264 has broad-spectrum antitumor activity[1].
Target: IC50: 188 nM (Transforming acidic coiled-coil 3 (TACC3))[1] Kd: 1.5 nM (TACC3)[1]
In Vivo: BO-264 (25 mg/kg; oral administration; daily; for 3-4 weeks; female nude mice) treatment shows a significant suppression of tumor growth. BO-264 is well tolerated since treatment does not causes a significant body weight loss and organ toxicity[1]. Animal Model: Female nude mice injected with JIMT-1 cells[1] Dosage: 25 mg/kg Administration: Oral administration; daily; for 3-4 weeks Result: Showed a significant suppression of tumor growth.
In Vitro: BO-264 (500 nM; 48 hours; JIMT-1 cells) treatment induces a prominent increase (from 4.1% to 45.6%) in the fraction of apoptotic cells as assessed by Annexin V/PI staining[1]. BO-264 (500 nM; 24 hours; RT112 cells) treatment decreases ERK1/2 phosphorylation, which is a marker for activated FGFR signaling along with a strong mitotic arrest[1]. BO-264 inhibits cell viability with IC50 values of 190 nM, 160 nM, 120 nM, 130 nM and 360 nM for JIMT-1, HCC1954, MDA-MB-231, MDA-MB-436 and CAL51, respectively. BO-264 specifically targets breast cancer cells while sparing normal cells. BO-264 treatment significantly reduces the average colony number of JIMT-1 cells[1]. BO-264 inhibits the viability of cancer cells with FGFR3-TACC3 fusion with IC50 values of 0.3 μM and 3.66 μM for RT112 and RT4, respectively[1]. BO-264 exhibits a remarkable anti-cancer activity against more than 90% of the NCI267 60 human cancer cell lines representing nine different subpanels with GI50 values less than 1 μM[1]. BO-264 induces mitotic arrest (prominent induces p-Histone H3 (Ser10)), apoptosis (cleaved PARP) and DNA damage, causes aberrant spindle formation and reduces centrosomal localization of TACC3 in JIMT-1 cells[1]. Apoptosis Analysis[1] Cell Line: JIMT-1 cells Concentration: 500 nM Incubation Time: 48 hours Result: Induced a prominent increase (from 4.1% to 45.6%) in the fraction of apoptotic cells as assessed by Annexin V/PI staining. Western Blot Analysis[1] Cell Line: RT112 cells Concentration: 500 nM Incubation Time: 24 hours Result: Decreased ERK1/2 phosphorylation.

DC60859 MT-125(MT 125) MT125​​ is a brain-penetrant small-molecule inhibitor selectively targeting non-muscle myosin IIA/B (NMIIA/B) with >20-fold specificity over cardiac myosin. It demonstrates potent anti-glioblastoma activity by: (1) blocking tumor invasion and cytokinesis (inducing polyploidy), (2) disrupting mitochondrial dynamics to elevate ROS and trigger ferroptosis, and (3) sensitizing tumors to radiotherapy/kinase inhibitors via ROS-driven PDGFR/mTOR pathway activation. Subcutaneous administration achieves brain concentrations twice plasma levels (t1/2~10.5 hr) with no toxicity observed at 15× the therapeutic dose in rats. MT-125 monotherapy extends survival in GBM models, while combinations with PDGFR/PI3K inhibitors induce long-term remission (>40% mice). Its first-in-class mechanism, safety profile, and CNS bioavailability support clinical development for glioblastoma.
DC60781 TRPC6 activator compound 2 TRPC6 activator compound 2 is selective activator of TRPC6 that does not potentiate TRPC3 and mTRPC7. Comp2 is able to cross BBB.
DC66546 R-Sirpiglenastat R-Sirpiglenastat is the R- isomer of Sirpiglenastat(DRP-104).Sirpiglenastat (DRP104) is a broad acting glutamine antagonist. Sirpiglenastat has anticancer effects by directly targeting tumor metabolism and simultaneously inducing a potent antitumor immune response.
DC60597 AZD0780 AZD0780 is the first oral small molecule PCSK9 inhibitor for the treatment of hypercholesterolemia.
DC90056 PLX-5622 HCl form (water solubility form) PLX5622 is the HCl salt form of PLX-5622, which has better water solubility.PLX-5622 is a highly selective brain-penetrant CSF1R inhibitor (IC50=0.016 µM; Ki=5.9 nM) allowing for extended and specific microglial elimination, preceding and during pathology development.
DC65830 1-M-PES(1-Methoxy-5-methylphenazinium ethyl sulfate) 1-m-PES is an electron mediator which has higher stability of solutions than 1-Methoxy PMS. The stability in neutral to alkali conditions has been extremely improved with 1-Methoxy PES. 1-M-PES is a stable small-molecular compound and it has an equal or higher thermal stability than diaphorase. The 1-Methoxy PES solution can be stored long term.
DC65821 Upadacitinib hemihydrate Upadacitinib (ABT-494) is a potent and selective Janus kinase (JAK) 1 inhibitor with an IC50 of 43 nM, being developed for the treatment of several autoimmune disorders.
