This drug/treatment he speaks of is not a peptide nor is it the "PG92" enzyme. The mechanism of action is prostaglandin D2 inhibition (PGD2). I believe this dermatologist he is speaking of filed for a patent on PGD2 inhibition as a treatment for alopecia 4-5 years ago. More recently he has been able to confirm the presence of high amounts of PGD2 in bald human scalps.
I have done quite a bit of work on PGD2 inhibitors for asthma, without much success. It was a great concept that is just not panning out in the real world. Prostaglandins are tricky business. Its not going to be as simple as just inhibiting PGD2.
The research is interesting but hair loss is a mutlifactorial condition which is not likely to be solved by inhibiting PGD2. There may be some measure of efficacy, but I would not get too excited. Real world application of his theory will almost certainly be met with disappointment. But big pharma already knows this or they would be all over it. As is, he is shopping for someone to test his theory out for him.
