Scientists found new small molecules. These molecules stop certain proteins called beta-arrestins from working.

科學家發現了新型小分子。這些分子能阻止被稱為 beta-arrestins 的特定蛋白質運作。

Beta-arrestins help cells send signals. Before this, scientists could not stop these proteins with medicine. Now, they found three new chemicals. These chemicals stop the proteins but do not stop other important cell signals.

Beta-arrestins 負責幫助細胞傳遞訊號。在此之前，科學家無法使用藥物來阻止這些蛋白質。現在，他們發現了三種新型化學物質。這些化學物質能阻止蛋白質，但不會影響其他重要的細胞訊號。

One chemical is called Cmpd-5. It fits into a small hole in the protein. This changes the shape of the protein. Because the shape changes, the protein cannot connect to other parts of the cell.

其中一種化學物質稱為 Cmpd-5。它會嵌入蛋白質的一個小孔中。這會改變蛋白質的形狀。由於形狀改變，蛋白質便無法與細胞的其他部分連接。

This discovery is important for health. It can help doctors treat asthma. It can also help with heart problems and sugar problems in the body.

這項發現對健康至關重要。它能幫助醫生治療哮喘，也能協助處理心臟問題以及體內的血糖問題。

These new chemicals help scientists understand proteins better. They can use them to make new medicines.

這些新型化學物質幫助科學家更深入地了解蛋白質，並可用於研發新藥。
