Profiling elapid venoms for coagulation and paralysis modulators by liquid chromatography wi th post-column in vitro/in vivo bioassays and mass spectrometry
< p>Chemist Arif Arrahman has conducted research into the harmful effec ts of snake venom and how we can better understand and combat them. S nakebites remain a major health problem in many parts of the world an d can lead to paralysis, blood clotting problems, and even death.The research focused on the following questions: Which toxins in s nake venom cause these effects, and can we quickly identify them? Arr ahman also investigated whether a small drug candidate called varespl adib can block dangerous venom components, particularly those that af fect blood clotting.
The researcher demonstrated that certain c obra venoms contain toxins that impair blood clotting, and that most of these toxins originate from a group of enzymes called PLA₂. The research also showed that varespladib can reduce or block these harmf ul effects in many cobra venoms. Furthermore, combining laboratory ce ll tests with zebrafish tests helped identify toxins that cause paral ysis by affecting ion channels.
This knowledge can help doctors and healthcare providers treat snakebite victims more effectively, e specially in rural areas. The results also support the development of varespladib as a potential first-aid treatment before patients reach the hospital. Besides snakebites, pharmaceutical researchers can ben efit from this, as toxins with potent effects on the body can inspire new drugs.
