NOTES

The concentration applied was given as 66.6nmol/cm2. I have converted this to mg for the database. They also gave the Kp as 40.44E-3 cm/h, but I have not included this until I check how the Kp was calculated. More than one cell was run for each compound but the actual numbers were not given.
