But what we really have: One Scientist (myself) Enough resources for a lavish retirement in Caribbean Islands Getting old – not much time left
Questions in my mind: Do I develop one Molecule at a time? Do I develop all the Drugs at one shot? Platform Technology? What area do I apply this Technology?
Status in the early 2000 Efficacious Toxic I wanted to increase the efficacy and reduce the toxicity i. e. Increase the Therapeutic Index Drugs entering market Examples

Prodrugs(? ) of Propofol Mr. Jackson wanted a good night sleep US Patent No. 8, 173, 840
Propofol Dose Selection Drug Low Mid High Propofol 10 mg/kg 15 mg/kg 20 mg/kg Lysine Ester of Propofol 40 mg/kg 45 mg/kg 50 mg/kg Proline Ester of Propofol 25 mg/kg 30 mg/kg 35 mg/kg Glycine Ester of Propofol 30 mg/kg 35 mg/kg 40 mg/kg 10 Rats each, all doses, Propofol molar equivalent
Propofol Efficacy Studies Mr. Jackson wanted low toxicity Drug Low (min)/ No. died Mid (min)/ No. Died High min)/ No. Died Propofol 0 0 123 ± 34 0 178 ± 30 0 Lysine Ester of Propofol 0 0 0 5 546 ± 0 9 Proline Ester of Propofol 282 ± 162 1 421 ± 113 0 641 ± 138 2 Glycine Ester of Propofol 532 ± 217 0 300 ± 211 0 641 ± 138 1 Time of righting reflex (seconds)
Conclusions – Propofol Studies • Mr. Michael Jackson only wanted a good night sleep • Doses administered to him were toxic. • If he had used Glycine Ester of Propofol, he would have had a long night sleep, and would come out of the sleep unscathed. • Further studies in humans are warranted.
