Abstract
Description
Cucurbituril compounds and their medical uses Technical Field
[0001] The present disclosure belongs to the field of medicine, and particularly relates to cucurbituril compounds and their medical uses. Background Art
[0002] Muscle relaxation is one of the three essential elements of general anesthesia. While muscle relaxants meet the needs of endotracheal intubation and surgery, they also pose a safety risk: residual muscle relaxation, which can lead to subjective discomfort in patients and a series of pulmonary complications such as hypoxemia, regurgitation, and aspiration. To reduce the incidence of residual muscle relaxation, measures such as the use of intermediate- and short-acting muscle relaxants, optimized intraoperative muscle relaxation management, postoperative antagonism of the effects of muscle relaxants, and objective perioperative muscle relaxation monitoring are often used. These measures have resulted in progress in addressing this clinical challenge.
[0003] Postoperative muscle relaxant antagonism refers to the use of muscle relaxant antagonists to reverse the residual effects of non-depolarizing muscle relaxants. Currently, commonly used muscle relaxant antagonists can be roughly divided into two categories: one is competitive muscle relaxant antagonists, including neostigmine, an acetylcholine inhibitor; the other is selective muscle relaxant antagonists, including sugammadex sodium, an antagonist for steroid muscle relaxants, and cysteine, an antagonist for benzylisoquinoline muscle relaxants.
[0004] The prior art WO2012051407A discloses a class of non-closed-ring CB[n]-type molecular containers with a cucurbituril structure, namely Calabadion2, which can efficiently bind to benzylisoquinoline and steroidal muscle relaxants, and by covering the quaternary ammonium sites of benzylisoquinoline and steroidal muscle relaxants, prevent the binding of muscle relaxants to neuromuscular cholinergic receptors, thereby rapidly reversing the muscle relaxant effect.

[0201] The term "oxo" refers to a =0 substituent.
[0202] "Substituted" means that one or more hydrogen atoms, preferably up to 5, more preferably 1 to 3 hydrogen atoms in a group are replaced independently of one another by a corresponding number of substituents. It goes without saying that the substituents are only in their possible chemical positions, and a person skilled in the art can determine (by experiment or theory) whether substitution is possible or not without undue effort.

[0366] 3. Experimental Methods
[0367] Quarantine-qualified SPF male Sprague-Dawley rats were housed at a room temperature of 22 ± 0.5°C, with a ventilation rate of 20–50 / h and an airflow velocity of 0.05–0.18 m / s, and a 12 / 12-hour light / dark cycle. Acclimate to the animal facility for at least three days, housing six rats per cage. Experiments were initiated when rats weighed between 220 and 250 g.
[0368] Reconstitute the test sample in 0.9% sodium chloride. Weigh the required amount of test sample after conversion based on the content. Dissolve it in 0.9% sodium chloride injection (within 30 minutes), then mix thoroughly using a vortex mixer. Reconstitute CB2 in purified water.
[0369] Actual weighed drug weight (mg) = dosage preparation concentration A (mg / mL) × solvent volume (mL) / content (%)
[0370] Rats were randomly divided into CB2, compound 2, compound 3, and neostigmine groups, with 4 rats in each group (based on the actual number of rats in each group), and the administration volume was 2 mL / kg.
[0371] CB2 (prepared using the known method "WO2012051407A2") has the following structure:
[0372] After anesthesia, the rats were isolated from the sciatic nerve and gastrocnemius muscle. The sciatic nerve was stimulated and muscle tension signals were recorded using a tension transducer. Endotracheal intubation was performed and mechanical ventilation was administered using a small animal ventilator. After a period of stable muscle tension signal recording, medication was administered: the initial dose was 2 times the ED. 90 A dose of 0.8 mg / kg of muscle relaxant (cisatracurium) is given. The muscle tension curve should decrease at this time. Antagonists (test substance and neostigmine) are injected 30-60 seconds after administration. When the muscle tension curve recovers to more than 95%, ED is given. 90 A muscle relaxant (succinylcholine) dose (0.9 mg / kg) should be administered. A decrease in muscle tone should be observed, and the experiment can be stopped when muscle tone naturally recovers to above 95%. Muscle tone signals should be continuously recorded during this period, and statistical analysis should be conducted on indicators such as onset time and clinical efficacy. The reversal of the muscle relaxant effect of the antagonist should be determined and compared by comparing muscle tone signals after administration.

Set the input signal to tension, and the parameters to square wave, fine voltage, train stimulation, 0.05 ms delay, 0.2 ms pulse width, 2 Hz frequency, 0.225 ± 0.025 V intensity, 0 intensity increment, 4 train lengths, 12 s main cycle, 30,000 pauses, and record muscle contraction curves. Maintain the muscle and nerve moist with saline solution throughout the measurement, rehydrating every 3-5 minutes.
[0382] 4.5 Connect to ventilator, inject muscle relaxants and antagonists
[0383] Wipe the ventilator tube port with alcohol, cut the neck skin, find the jugular vein and trachea, cut the trachea, connect the ventilator, and set the parameters to tidal volume 6mL, respiratory time ratio 5:4, and respiratory rate 80 times / min. After stabilizing for about 5 minutes, administer the drug through the jugular vein. According to the reference settings, give 2 times the ED for the first time. 90 Doses of muscle relaxant (cisatracurium) are given. The muscle tension curve should decrease at this time. Antagonist (test substance or neostigmine) is injected 30-60s after administration. When the muscle tension curve recovers to more than 95%, ED is given. 90 The experiment can be stopped after the muscle tension curve recovers to more than 95%. The muscle tension curve is continuously recorded during this period.
