Tubulysin B is an agent of potent microtubule destabilizing and highly cytotoxic peptide isolated from the myxobacteria Archangium geophyra and Angiococcus disciformis.
Tubulysin family are originally isolated from the myxobacteria Archangium geophyra and Angiococcus disciformis, and are potent microtubule destabilizing agents.
I3IN-002是一种小分子IGF2BP3抑制剂,IC50值在 SEM 细胞中约为 2 μM。该化合物能够干扰与m6A修饰的mRNA的相互作用,破坏目标基因(如CDK6、MYC和BCL2)的稳定性,进而抑制白血病细胞生长,诱导细胞周期停滞,并促进细胞凋亡。I3IN-002有潜力用于B细胞急性淋巴细胞白血病的研究。
CMP3a is a NEK2 kinase inhibitor. CMP3a efficiently attenuated GBM growth in a mouse model and exhibited a synergistic effect with radiotherapy. Targeting NEK2 attenuates glioblastoma growth and radioresistance by destabilizing histone methyltransferase E
DAP-81 is a diaminopyrimidine derivative that targets PLKs, destabilizing kinetochore microtubules. Other spindle tubules are stabilized, resulting in monopolar mitotic spindles. In vitro, DAP-81 inhibits Plk1 at an IC50 of 0.9 nM. DAP-81 is currently in ongoing preclinical evaluations.
PC-046 is a potent tubulin-binding agent, which was originally identified for development based on selective activity in deleted in pancreas cancer locus 4 (DPC4/SMAD4) deficient tumors. PC-046 has growth inhibitory activity in a variety of tumor types in vitro, and efficacy in SCID mice was shown in human tumor xenografts of MV-4-11 acute myeloid leukemia, MM.1S multiple myeloma, and DU-145 prostate cancer. Pharmacokinetic studies demonstrated relatively high oral bioavailability (71 %) with distribution to both plasma and bone marrow. No myelosuppression was seen in non-tumor bearing SCID mice given a single dose just under the acute lethal dose. The COMPARE algorithm in the NCI-60 cell line panel demonstrated that PC-046 closely correlated to other known tubulin destabilizing agents (correlation coefficients ≈0.7 for vincristine and vinblastine). Mechanism of action studies showed cell cycle arrest in metaphase and inhibition of tubulin polymerization. Overall, these studi......
