Currently, malignant tumors remain one of the major life-threatening diseases. Cancer treatment, while much progress has been made, has not been able to treat cancer at all. Although the anticancer drugs on the market at present have certain curative effect, most of them are cytotoxic drugs and have serious toxic and side effects. Therefore, it is urgent to develop a novel anticancer drug targeting from an effective tumor target to study targeting.
Most studies on CRM1 have used the natural product CRM1 inhibitor leptomycin b (lmb). Has high toxicity to tumor cells, but is difficult to accept by animals due to obvious gastrointestinal toxicity. Inhibitors of nuclear export can have beneficial effects on neoplastic disorders and other hyperplastic disorders.

CRM1 can inhibit tumor suppressor proteins, export several key proteins associated with many inflammatory processes, mediate retinoid X receptor a (rxra) transport, inhibit activation of a range of transcription factors like ICp27, E2F4, KL5, YAP1, ZAP to affect gene expression, mediate transport of key neuroprotective proteins, CRM1 controls nuclear localization and thus the activity of various DMA metabolisms, CRM1 is also associated with other disorders. Complete maturation of many viruses also requires complete nuclear export, mediated primarily by CRM 1.
In view of the above, the present invention provides a nuclear transport modulator derivative or a pharmaceutically acceptable salt thereof, an azole compound having a novel structure and a function of inhibiting CRM1 protein, which is a CRM1 protein inhibitor, can block tumor cell proliferation, induce tumor cell apoptosis, and is useful for treating various diseases, disorders or conditions associated with abnormal cellular responses triggered by inappropriate nuclear transport.

In the case of capsules, tablets and pills, the pharmaceutical compositions may also comprise buffering agents. Solid compositions of a similar type may also be employed as fillers in soft and hard-filled gelatin capsules using excipients such as lactose or milk sugar as well as high molecular weight polyethylene glycols and the like.
Oral liquid dosage forms of this embodiment include pharmaceutically acceptable emulsions, microemulsions, solutions, suspensions, syrups and elixirs. In addition to the active ingredients, the liquid dosage forms may contain inert diluents commonly used in the art such as, for example, water or other solvents, solubilizing agents and emulsifiers such as ethyl alcohol, isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propylene glycol, 1, 3-butylene glycol, oils (especially cottonseed, groundnut, corn, germ, olive, castor, and sesame oils), glycerol, tetrahydrofuryl alcohol, polyethylene glycols, fatty acid esters of sorbitan, and mixtures thereof. The oral composition of this embodiment may also include adjuvants such as wetting agents, emulsifying agents, suspending agents, sweetening agents, flavoring agents, coloring agents, flavoring agents and preserving agents.
Formulations for rectal or vaginal administration in accordance with the present embodiments may be presented as a suppository, which may be prepared by mixing one or more inhibitors with one or more suitable non-irritating excipients or carriers comprising, for example, cocoa butter, polyethylene glycol, a suppository wax or salicylate, and which is solid at room temperature and liquid at body temperature and, therefore, will melt in the rectum or vaginal cavity and release the active agent. Formulations suitable for vaginal administration also include pessaries, tampons, creams, gels, pastes, foams or spray formulations containing such carriers as are known in the art to be appropriate.
Regardless of the route of administration chosen, the inhibitors of the invention (which may be used in their appropriate hydrated forms) and/or the pharmaceutical compositions of the invention may be formulated into pharmaceutically acceptable dosage forms by conventional methods known in the art.
These compositions may also contain adjuvants such as preserving, wetting, emulsifying, and dispersing agents. Various antibacterial and antifungal agents can be added to prevent the action of microorganisms, such as parabens, chlorobutanol, phenol, sorbic acid, and the like. Tonicity adjusting agents such as sugars, sodium chloride, and the like may also be required in the composition. In addition, prolonged absorption of the injectable pharmaceutical form can be brought about by the addition of agents delaying absorption, for example, aluminum monostearate and gelatin.
In order to prolong the effect of the drug, this embodiment requires slowing the rate of absorption of the drug by subcutaneous or intramuscular injection. For example, absorption of a parenterally administered drug is delayed by dissolving or suspending the drug in an oil vehicle. This example allows for variations in the actual dosage level of the active ingredient of the pharmaceutical composition of the invention to achieve an effective amount of the active ingredient to achieve the desired therapeutic response without poisoning the patient for the particular patient, composition, and mode of administration.
The concentration of the compound of this embodiment in a pharmaceutically acceptable mixture will vary depending on a number of factors, including the dose of the compound administered, the pharmacokinetic characteristics of the compound used, and the route of administration. In another aspect of this embodiment, combination therapy is provided wherein one or more additional therapeutic agents are administered with the proteasome inhibitor of the present invention. Such combination therapy may be achieved by the simultaneous, sequential or separate administration of the treatment components.
