Obat obesitas 'kuda troya' tingkatkan penurunan berat badan pada tikus

Para ilmuwan telah mengembangkan pengobatan obesitas hibrida yang menggunakan sinyal GLP-1 dan GIP untuk mengirimkan peningkat metabolisme langsung ke dalam sel. Uji coba awal pada tikus menunjukkan penurunan berat badan yang lebih besar dan kontrol gula darah yang lebih baik dibandingkan terapi standar. Pendekatan ini bertujuan untuk mengurangi efek samping dengan membatasi kerja obat pada area yang ditargetkan.

Para peneliti di Helmholtz Munich menciptakan senyawa tersebut dengan menghubungkan molekul berbasis inkretin dengan lanifibranor, yaitu agonis pan-PPAR. Desain ini berfungsi seperti kuda troya, yang memungkinkan obat tambahan tersebut memasuki sel melalui reseptor GLP-1 atau GIP sebelum mengaktifkan sakelar yang mengatur metabolisme lemak dan gula di dalam nukleus.

People who lose weight using GLP-1 medications such as Ozempic and Wegovy may be judged more negatively than those who lose weight through diet and exercise — and even more negatively than people who do not lose weight at all — according to a new study led by Rice University psychologist Erin Standen.

Three Cochrane reviews commissioned by the World Health Organization evaluate GLP-1 receptor agonists like tirzepatide, semaglutide, and liraglutide for weight loss in people with obesity. The drugs show substantial weight reduction compared to placebo, but researchers note limitations in long-term data and industry funding influences. Side effects such as nausea are common, raising questions about broader access and safety.

An investigation by India Today highlights how weak enforcement of regulations allows easy access to prescription-only weight-loss drugs in India, leading to increased misuse.

Researchers at Vanderbilt Health discovered that both popular weight loss drugs and bariatric surgery significantly reduce fat mass while causing modest losses in fat-free mass, including muscle, in patients with obesity. The findings, based on over 3,000 patients, show improvements in overall body composition over 24 months. Maintaining this balance is crucial for long-term health, the study emphasizes.

Researchers in Barcelona report that the lipid drug pemafibrate and the blood-pressure medicine telmisartan reduced diet-induced liver fat in rats and in a zebrafish model of fatty liver disease, with a half-dose combination performing as well as full doses of either drug alone. The work, published in Pharmacological Research, also describes a role for the PCK1 protein in telmisartan’s liver effects and argues that clinical trials would be needed to confirm any benefit in people.

University of Utah scientists report that a radical SAM enzyme known as PapB can join the ends of certain therapeutic peptides to form stable, ring-shaped structures. In experiments described in ACS Bio & Med Chem Au, the enzyme macrocyclized GLP-1-like peptides—including versions containing nonstandard amino acids found in some modern incretin drugs—an approach the researchers say could help make GLP-1 medicines such as semaglutide (Ozempic and Wegovy) more resistant to breakdown.
