Pyrazoline and Pyrazoline Derivatives as Anti-Cancer Agents: Synthesis and Biological Activities: A Compressive Review

Background: A heterocyclic molecule containing five rings, three carbon atoms, two nitrogen atoms, and a single endocyclic bond is called pyrazoline. Because of its intriguing electrical characteristics and potential for dynamic applications, pyrazoline is one type of electron-rich nitrogen carrier that is becoming more and more popular. This study synthesizes pyrazoline derivatives using a variety of techniques to demonstrate a highly biological function. Objective: Pharmaceutical chemistry has found the study of the biological activity of pyrazoline derivatives to be an interesting field. Pyrazolines find utility in numerous multipurpose applications. It has been discussed to examine the current study of patent literature on pyrazoline derivatives (2000–2024) that describes the introduction, general approach, synthesis scheme Structureactivity and relationship, marketed drug, and patents on anticancer activities. Conclusion: A recognized heterocyclic chemical is pyrazolines. Three carbon atoms and two adjacent nitrogen atoms make up the five-membered ring that is pyrazoline. A variety of methods are available to determine its synthesis. Extensive studies have been conducted in this field since it has been found that many pyrazoline derivatives have a crucial biological effect on anticancer activity. The application of pyrazoline as an anticancer agent is a fascinating moiety with a wealth of potential applications for further research by scientists.
