Summary: We synthesized a new tubulin polymerization inhibitor, RS6077, which inhibited the growth of multiple cancer cell lines without affecting non-transformed cells. It induced G2/M phase arrest in both transformed and non-transformed cells, but showed selective induction of cell death in transformed cells that fail to complete mitosis. RS6077 also inhibited the growth of a lymphoma xenograft model and demonstrated good metabolic stability.

Summary: The study verified the antitumor activity of a specific γ-tubulin inhibitor, gatastatin, which showed weaker cytotoxicity compared to conventional microtubule inhibitors. Screening revealed that the Plk1 inhibitor, BI 2536, significantly increased the cytotoxicity of gatastatin, leading to cell cycle arrest at mitosis with abnormal spindles and mitotic cell death. Co-treatment with Plk1 and γ-tubulin inhibitors may offer a novel approach to cancer chemotherapy.

Summary: Novel dual PDE4/tubulin inhibitor 4r, derived from trimethoxyphenylbenzo[d]oxazoles, exhibited satisfactory antiproliferative activities against glioma and lung cancer cells by inducing apoptosis and disrupting the microtubule network. Its mechanism of action involved down-regulation of cyclin B1 and its upstream regulator gene cdc25C.

Summary: Metastatic breast cancer (mBC) is responsible for >90% of breast cancer-related deaths. The effectiveness of microtubule-targeting agents (MTAs) in mBC treatment is limited by primary or acquired resistance. This study evaluated the potential of methyl N-(6-benzoyl-1H-benzimidazol-2-yl)carbamate (BCar) as a novel MTA for MTA-resistant mBC. The results showed that BCar selectively killed breast cancer cells and had a wider therapeutic window compared to clinical MTAs docetaxel and vincristine.

Summary: The novel colchicine derivative CR42-24 has shown selective cytotoxicity against various cancer cell lines, with high activity in bladder cancer cell lines. Monotherapy with CR42-24 in an aggressive urothelial carcinoma xenograft model effectively controls large tumors. The combination of CR42-24 with standard chemotherapies gemcitabine and cisplatin demonstrates high synergistic effects, increasing its potential as a novel treatment for urothelial carcinoma.

Summary: In this study, sixteen novel conjugates containing tubulin inhibitor and matrix metalloproteinase inhibitor were synthesized and evaluated for their activity. Compound 9e showed the most potent activity against various human cancer cells, including multidrug-resistant tumor cells, and exhibited lower cytotoxicity towards normal liver cells. It strongly inhibited tubulin polymerization, induced cell apoptosis and cell cycle arrest, and displayed inhibition of cell migration and moderate activity towards MMP-2, MMP-3, and MMP-9. Moreover, it induced apoptosis via the mitochondria-dependent pathway and caused ER stress. In vivo, 9e showed significant antitumor efficacy without systemic toxicity. Overall, compound 9e is a novel and promising agent for cancer therapy, acting as a dual MMPs and tubulin inhibitor.

Among them, the hit compound D8 showed potential in inhibiting the growth of several cancer cell lines, with comparable activity to Colchicine and CA-4P. The results indicated the potential for further modification of tubulin-related anti-cancer agents and therapeutic approaches.

Summary: The study found that GDC-0980 can effectively inhibit the survival of human GBM cells and induce apoptosis, independent of ER stress-mediated DR5 activation. It is suggested that GDC-0980 may block the inhibitory effect on protein synthesis through inhibiting PERK expression, leading to an intensification of translation and an increase in apoptosis. Additionally, CHOP stimulates protein synthesis and increases apoptosis.

Summary: The study synthesized 22 compounds with various substitutions on imidazo[2,1-b][1,3,4]thiadiazoles and investigated their potential cytotoxic activity in leukemia cell lines. Two compounds showed the most cytotoxic effect against leukemia cells, T-lymphocyte cells, and cervix carcinoma cells, with IC50 values ranging between 0.79 and 1.6 μM. These compounds induce apoptosis through phosphatidylserine externalization and caspase-3 activation, and binding studies showed strong interactions with the active sites of TGF-beta type I receptor kinase domain.

Summary: In this study, a curcumin derivative called ST03 exhibited better bioavailability and stability compared to curcumin. ST03 demonstrated anticancer effects by inducing reactive oxygen species (ROS) and activating the intrinsic apoptotic pathway in ovarian cancer cells. ST03 also inhibited the migration of ovarian cancer cells. These findings suggest that ST03 has potential as a promising drug candidate for anticancer therapies.

Summary: Despite available treatment options, blood cancer still has high mortality rate due to relapse and aggressive nature of the disease. Elevated levels of HSP90 have been associated with poor prognosis in leukemia and lymphoma. The HSP90 inhibitor, SP11, demonstrated cytotoxicity against leukemic cells and induced cell death through apoptosis, while having minimal effect on normal cells. SP11 also showed potential in reducing tumor burden in mouse models without apparent toxicity.
