GLP-1 / Weight Loss Agonists

Syn-Ake- Summary
- Survodutide is a once-weekly GLP-1/glucagon dual receptor agonist developed by Boehringer Ingelheim and Zealand Pharma. Phase 2 trials demonstrated up to 18.7% body weight reduction at 46 weeks, among the highest reported for a dual agonist. It is being studied for obesity and MASH (metabolic dysfunction-associated steatohepatitis), where the glucagon component drives hepatic fat clearance.
- Syn-Ake is a synthetic tripeptide that mimics waglerin-1, a peptide found in the venom of the Temple viper (Tropidolaemus wagleri). It acts as a reversible antagonist of muscular nicotinic acetylcholine receptors, temporarily reducing facial muscle contraction and smoothing dynamic wrinkles. Often called a 'synthetic Botox' in cosmetic marketing.
