Definition: The phrase '380. 1 Methyl 3 (pyridin 2 yloxy) 1H indole; 1558047 17 8' is a term used in the pharmaceutical industry to describe a compound known for its therapeutic benefits. It's often abbreviated as '380'. Here’s how it looks:

- 380 (three hundred eighty) - A number with two or more digits. - Methyl - The chemical symbol of methyl, which is a common alkyl group in organic compounds. - 2 Methyl 3 - This term refers to the compound's hydroxy group being composed of a methyl and three other carbon atoms (2methyl3). Now, let's take an edgy example sentence from the same context: "Imagine someone in charge of a pharmaceutical trial had to choose between three options: a new drug that was 1558047 powerful but could potentially be toxic, or one with the potent effects of the other. The choice would be like deciding between 2 Methyl 3 (pyridin 2 yloxy) indole and 1558047 17 8 - which could be dangerous but might also have immense potential benefits."
