Example Embodiment

[0030] Example: Animal model and treatment of hair loss after chemotherapy

[0031] 1. Experimental materials

[0032] The experimental animals were SPF Km mice aged 4-6 weeks, provided by the Experimental Animal Center of Sun Yat-Sen University, and raised at room temperature.

[0033] Cyclophosphamide and paclitaxel for injection were purchased from Sun Yat-sen University Cancer Hospital, and other commercially available products can also be used;

[0034] Therapeutic drugs: 17-propenylamino-17-demethoxygeldanamycin (17-AAG), purchased from SIGMA.

[0035] Others: physiological saline; chloral hydrate; heating equipment such as water bath.

[0036] 2. Experimental methods and results

[0037] The experimental mice were randomly divided into five groups: control group, cyclophosphamide chemotherapy experimental group (no drug treatment), cyclophosphamide chemotherapy + drug treatment group, paclitaxel chemotherapy group (no drug treatment), paclitaxel chemotherapy + drug treatmen...

Abstract

The invention relates to the new use of geldanamycin derivative, particularly to an application of the geldanamycin derivative in preparing drugs for treating chemotherapy-induced alopecia. The invention provides an application of geldanamycin derivative 17-allylaniino-17-demethoxy-geldanamycin (17-AAG) in preparing drugs for treating chemotherapy-induced alopecia. The inventive geldanamycin derivative 17-AAG can be used for developing new drugs for treating chemotherapy-induced alopecia, which have reliable safety and can remarkably improve the life quality of chemotherapy patients and relieve mental pressure of patients, so as to better cooperate with cancer treatment.

Description

technical field [0001] The present invention relates to the new application of geldanamycin derivatives, especially the application of geldanamycin derivatives in the field of chemotherapy-induced alopecia. Background technique [0002] Hair is composed of the hair root, the hair bulb (germinal center) and the hair shaft. Cells proliferate within the hair bulb, where the hair grows from the root through the scalp. The end result is just a strand of tight keratin. Hair growth is divided into three stages. The first stage is anagen, which is the growth phase and 85-90% of human hair follicles are in anagen. Each hair follicle contains a spherical base of mitotically active mother cells. From these bases, all hair stem cells differentiate and grow. The cells move in rows towards the upper part of the hair bulb and elongate vertically. Eventually they are forced upwards and burrow out of the skin's surface. Human hair bulb cells divide on average every 12 to 24 hours. Du...
