Definitions
- the present invention relates to anti-tumor multidrug resistance of heteroarylamide compounds as novel microtubule inhibitors and for the treatment of cervical cancer, colon cancer, ovarian cancer cells, nephroblastoma, endometrial cancer , uterine sarcoma, human T lymphoma, and microtubule inhibitors in clinically treatable cancers such as cholangiocarcinoma, brain cancer, esophageal cancer, head and neck cancer, colon cancer, kidney cancer, lymphoma, muscle cancer, nervous system cancer, Uses of cancers of pancreatic cancer, pleural cancer, skin cancer, thyroid cancer, urinary tract cancer, uterine cancer, and female vulvar cancer, and protein-drug molecular complexes.
- microtubules Due to the important role of microtubules in cell mitosis, microtubules are considered to be one of the most important targets for anticancer drugs (1-3). Microtubule inhibitors have been widely used in the treatment of various tumors by binding to microtubules and further affecting the function of microtubules (4, 5). Microtubule inhibitors are classified into different classes according to their binding sites: paclitaxel binding site, vinca alkaloid binding site, and colchicine binding site. (6-8). Paclitaxel binding site inhibitors disrupt mitosis by enhancing microtubules and preventing microtubule depolymerization (9). The other two binding site inhibitors can depolymerize microtubules and block the cell cycle in mitosis (10-13). These inhibitors, particularly paclitaxel and vincristine, are widely used as cancer chemotherapy drugs. Unfortunately, more than half of cancer patients eventually develop multidrug resistance (MDR) for chemotherapy drugs (14, 15).
- MDR multidrug resistance
- ABC protein acts as a cell membrane transporter to reduce drug accumulation in cancer cells by pumping different compounds.
- Key members of the ABC transporter family include MDR1/P-gP/ABCB1 (multidrug resistance gene 1, P-glycoprotein), MRPs/ABCCs (multidrug resistance-associated protein), BCRP/ABCG2 (breast cancer resistance protein) ) (19, 20). With the overexpression of these transfer pumps, the efflux of the drug increases, leading to drug resistance. MDR is an inevitable obstacle to the success of chemotherapy.
- Microtubule inhibitors are widely used as chemotherapy drugs for the clinical treatment of cancer.
- MDR multidrug resistance

- the mitotic blocking function of I-28 was further verified from other cell lines.
- I-28 may interfere with the cytoskeletal system.
- Microtubules, spindles, eutrosomes, and microtubule organizing centers (MTOCs) can be formed separately in mitosis. The presence of two centrosomes in each cell after compound treatment indicates that the spike-like spots are not centrosomes (Fig. 2C, 2D).

Conformation.

- Toxicity (1) With more available compounds that target many other components of the tubulin-microtubule complex, this is certainly an important aspect of leveraging its anticancer potential by combining two or more targets in the same system. A synergistic effect of the drug can be achieved.
- I-28 A series of small molecules represented by I-28 exhibit promising pharmacological effects against MDR both in vitro and in vivo.
- the molecular mechanism of the inhibitory function of I-28 is different from that of previously reported anti-MDR drugs, which bind to the colchicine binding site of tubulin, thereby depolymerizing microtubules and affecting spindle formation.
- Our data show that it can be further developed into a new skeleton for cancer, especially for MDR cancer therapeutics.
