The
following is prepared by Dr. Proctor, a leading specialist in hair loss treatments who has
many patents to his credit.
The Patents:
1) Method for Stimulating Hair Growth using GLH-Cu Complexes., Picard, Loren, US Patent
#5,117,061, assigned to Procyte Corporation, Pullman, Washinton.
2) GLH Pharmaceutical Compostitions and Compounds, US Pat# 5,214,032, Picard, L. to
Procyte Corporation.
Note: This is the " Iamin " or " Tricomin " patent. I get a lot of
questions about this compound, which the media does know. Lots of you have probably heard
of it. Iamin is the Tripeptide Glycine-Histidine-Lysine complexed with a metal. Another
name for it is "Liver Cell Growth Factor". It is a potent SODase. Procyte
reports significant hair-growth stimulating ability in their animal and clinical trials.
Like SODase itself, Iamin is a potent antiinflammatory agent.
3) His-Gly-Gly Peptide and Derivatives Thereof for Hair Growth. Kronholm et al, US Patent
#5,252,559, to: Procter and Gamble Co.
Note: Ah-ha, the largest maker of hair care stuff in the world is getting into the act.
Like Iamin, another metal- binding tripeptide with SODase activity. AKA " Copper-
Binding Peptide ". The structure is Histidine-Glycine- Glycine.
An interesting patent to me personally: in patents #4 and 6 below, we claim basic
metal-binding peptides as a class and give as one example His-gly " and the like
".Our US priority date is 1986, which antedates all the others.
4) Hair Growth Stimulation with Nitroxide and Other Radicals. EPO pat# 327263 B1.,
Proctor, P.
Note: All sorts of stuff. Basic peptides (e.g. Iamin ), SODases, nitroxide spintraps and
spin labels, PBN, etc. acetylcysteine, radical scavengers, use of antiandrogens with hair
growth stimulators, etc.,etc.. A " prime patent " which has caused several
subsequent drug company patents to be rejected because of "prior art". Gives you
some Idea of where our research was several years ago.
5) Topical TEMPO, Proctor, P. US pat# 5,352,442.
Note: Unlike the Europeans, the US patent office won't give prime patents in this area and
is making us patent everything individually ( which is how P was able to step in ). This
is the first US patent so far. Priority is what counts and we've sure got that.
TEMPO and related compounds are SODases, among other things. Researchers at the National
Cancer Institute report that TEMPO and TEMPOL, also covered in this patent, prevent hair
loss in radiation treatment. No, neither compond is in any of our formulas yet. However, a
related compound, NANO, is in all our formulations.
6) Topical SOD for Treating Hair Loss,
Proctor, P. US Pat# 5,40,876
Abstract: SOD for treating hair loss is disclosed. The SOD has utility in a topical
pharmaceutical formulation for the cosmetic treatment of hair loss and the cosmetic
stimulation of hair growth. The SOD comprises copper salicylate, copper aspirinate,
indomethacin copper, or a metal complex of an aminoacid and a transition metal.
This is the prime patent in this area. Even incorporates Trichomin, etc.
7) The most recent patent from the holder of the "Trichomin" patent.
Tissue Protective and Regenerative Compositions US Pat # 5,382,431 Issue Date: 1-17-95
Pickart; Loren R. Bellevue WA
8) I have been granted several more additional US patents for Nitrone and niroxide spin
traps and spin labels. As of this date (oct., '97 ) thye have not issued, but should do so
in the next several months. These agents are usful for a lot of other degenerative
conditions besides balding, BTW.
