Embodiment 1
[0013] Example 1: Preparation of 5-(N-2-phenylethylamino)-2-(4-methoxyphenyl)-2H-benzotriazole
[0014] (1) Dissolve p-methoxyaniline (2.48g, 20.14mmol) in 48ml of aqueous hydrochloric acid (4M), add sodium nitrite (1.67g, 24.17mmol) under ice bath conditions, and react for half an hour. Ammonium sulfamate (3.16 g) was slowly added to the system at 0°C and stirring was continued for half an hour. The pH of the solution was adjusted to 5-6 with sodium acetate, and o-phenylenediamine hydrochloride (3.33 g, 18.42 mmol) was added to the reaction system under ice-bath conditions, and stirred overnight. After the completion of the reaction as detected by TLC, adjust the pH to greater than 14 with sodium hydroxide solution, extract with ethyl acetate and water, combine the organic phases, and distill under reduced pressure to obtain a dry crude azo compound. The azo compound was dissolved with 40ml of pyridine, and 10g of anhydrous copper sulfate was added to 60ml of concentrated am...
Embodiment 2
[0017] Example 2: Preparation of 5-(N-2-phenylethylamino)-2-(4-methoxyphenyl)-2H-benzotriazole (hereinafter referred to as RS042) liquid
[0018]
[0019] Preparation method: under normal temperature and pressure, weigh 10g of propylene glycol, dissolve it in an appropriate amount of distilled water, then add 1.5g of RS042 and 0.01g of sodium benzoate according to the ratio of each component in the prescription, stir to dissolve, and finally add distilled water to 100ml, stir well, mix well, adjust the pH to 7.0 at the same time, fill in cans, seal, and inspect to get the finished product.
Embodiment 3
[0020] Example 3: Study on the curative effect of RS042 medicinal solution on patients with skin damage after radiotherapy for cervical cancer
[0021] There were 52 cases of cervical cancer, including 23 cases of squamous cell carcinoma and 29 cases of adenocarcinoma. They were randomly divided into an observation group of 26 cases and a control group of 26 cases. The observation group was 25 to 59 years old, with an average (44.2±9.6) years old, and the control group was 24 to 60 years old, with an average (45.7±8.5) years old. There was no significant difference in age comparison and pathological classification between the two groups, which were comparable. All patients were treated with linear accelerator X-ray external irradiation, point B DT40Gy~50Gy / 20~25 times / 4~5 weeks; intracavitary afterloading treatment, using 198Ir afterloading intracavitary radiotherapy, A point DT4 dose 30~36Gy / 5 ~6 times. Nursing guidance for each group of cases: keep the perineum clean and d...
