Very interesting, Ed. For me this says that we can aim for low logP compounds without worrying that potency will necessarily suffer.

- The active compounds appear to be contained within a circular quadrant
- A number of the most potency compounds have cLogP values ranging from 2 to 4.5
- Inactive compounds are mainly grouped around cLogP values of 1.5 and 3.5

@mattodd Deff worth a try to tweak the ether linked section of the molecule to increase water solubility. for example n-morpholinoethanol is about 20 USD for 5 grams and n-morpholinopropanol being 50 USD for a single gram - logp's of the finished molecules are 0.97 and ~2 respectively! @edwintse
