The invention provides compositions, methods and kits for the removal of harmful or irritating substances from bodily surfaces. Kits may include a composition containing capsaicin and a capsaicin-cleansing composition, e.g., a composition in which capsaicin is soluble.

Described herein are peptides that can be used to treat pain or increase pain sensitivity in subject in need of treatment. Additionally, peptides of the present disclosure can be administered with an analgesic agent and/or anesthetic agent. Peptides of the present disclosure are suitable for use when a subject in need of treatment has an injury, a chronic disease, a chronic inflammation, Morton's neuroma, operative/post-operative pain, or a combination thereof.

A nitrogen-containing derivative of substituted phenol hydroxyl acid ester is represented by formula (I). A salt of the compound of formula (I) has good water solubility, and in vivo, can rapidly and completely release substituted phenols having a pharmacological effect, which can improve the water solubility of substituted phenols, rapidly exert the pharmacological effects of substituted phenols in vivo, and has good safety. The method for preparing the above-mentioned compound is provided. This compound can also be used in the preparation of drugs that produce anaesthesia and/or sedative and hypnotic effects on humans and animals.

Disclosed are a pyridyl imidazobenzodiazepine propionate (compound 1) and the synthesis and use thereof. Also provided are intermediates for the preparation. Compound 1 provided by the present invention has an obvious venous anesthesia activity equivalent to that of the positive control drug remimazolam p-toluenesulfonate or remimazolam besylate. In addition, compound 1 can be significantly reduced in mouse model experiments, and same can even overcome common limb jitters, head tilting, opisthotonus and other side effects caused by the remimazolam besylate or remimazolam p-toluenesulfonate as a drug during development in preclinical animal experiments, thereby allowing same to be used in the preparation of intravenous anesthetics. The structural general formula of compound 1 is as follows, wherein each group and substituent are as defined in the description.
