Notes to Physician:

Section 5 - FIRE FIGHTING MEASURES
General Information:
As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Dust can be an explosion hazard when exposed to heat or flame. Flammable solid.
May burn rapidly with flare burning effect. May re-ignite after fire is extinguished. Containers may explode when heated. Risk of explosion if heated under confinement.
Extinguishing Media:
Use water spray to cool fire-exposed containers. For large fires, use water spray, fog or regular foam. Contact professional fire-fighters immediately. For small fires, use dry chemical, carbon dioxide, sand, earth, water spray or regular foam. Cool containers with flooding quantities of water until well after fire is out.

Section 6 - ACCIDENTAL RELEASE MEASURES
General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks:
Sweep up or absorb material, then place into a suitable clean, dry, closed container for disposal. Scoop up with a nonsparking tool, then place into a suitable container for disposal. Avoid generating dusty conditions. Remove all sources of ignition. Provide ventilation.

Section 7 - HANDLING and STORAGE
Handling:
Wash thoroughly after handling. Minimize dust generation and accumulation. Avoid contact with eyes, skin, and clothing. Empty containers retain product residue, (liquid and/or vapor), and can be dangerous. Keep container tightly closed. Keep away from heat, sparks and flame. Avoid ingestion and inhalation. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames.
Storage:
Keep away from sources of ignition. Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances.

Section 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION
Engineering Controls:
Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower. Use adequate general or local explosion-proof ventilation to keep airborne levels to acceptable levels.
Exposure Limits CAS# 2592-95-2: Personal Protective Equipment Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166.
Skin:
Wear appropriate protective gloves to prevent skin exposure.
Clothing:
Wear appropriate protective clothing to prevent skin exposure.
Respirators:
Follow the OSHA respirator regulations found in 29 CFR 1910.134 or European Standard EN 149. Use a NIOSH/MSHA or European Standard EN 149 approved respirator if exposure limits are exceeded or if irritation or other symptoms are experienced.

制备方法与用途

性质

1-羟基苯并三唑(HOBT)常温常压下为白色或灰白色结晶固体状。其羟基在碱性条件下可以转变为相应的有机盐,因此可以在有机合成中与烷基卤代烃发生亲核取代反应生成烷基化衍生物。

应用

1-羟基苯并三唑(HOBT)广泛应用于有机合成和医药化学领域,常作为多肽类药物分子及生物活性分子的合成与衍生化的重要中间体。此外,它还用于化妆品生产中。

合成

在一个干燥的反应烧瓶中,将25毫摩尔水合肼(1.2毫升)加入到邻硝基氯苯(5毫摩尔)溶解在1-庚醇(10毫升)中的溶液里。然后,在110-120℃下搅拌该溶液5小时。反应结束后,用40%的NaOH水溶剂中和反应混合物,并在减压下除去多余的肼和1-庚醇。将pH值调节至3.2-3.5后,通过过滤收集沉淀产品。随后,使用冷却的5%氯化钠水溶液清洗沉淀物,最后在二氯甲烷和甲醇中进行重结晶提纯,即可得到目标产物分子。

    LIM 激酶 LIMK1 和 LIMK2 已成为开发抑制剂的有前景的靶标,具有治疗多种主要疾病的潜在应用。 LIMK 作为 Rho-GTPase 家族小 G 蛋白的下游效应子,以及肌丝蛋白丝切蛋白(一种肌动蛋白解聚因子)的主要调节因子,在细胞骨架重塑中发挥着至关重要的作用。在本文中,我们描述了新型四氢吡啶吡咯并嘧啶 LIMK 抑制剂的概念、合成和生物学评价。首先构建同源模型是为了更好地理解我们初步化合物的结合模式并解释生物活性的差异。生成了包含 60 多种产品的库,并在中低纳摩尔范围内测量了酶活性。然后对最有前途的衍生物进行了肌动蛋白丝切蛋白磷酸化抑制的评估,从而鉴定出其在激酶选择性组中对 LIMKs 表现出优异的选择性。我们还证明它通过干扰肌动蛋白丝来影响细胞骨架。使用三种不同细胞系对该衍生物进行的细胞迁移研究显示出对细胞运动的显着影响。最终,解决了与LIMK2复合的激酶结构域的晶体结构
