Botanical and bacterial extracts displaying retinol-like activity
Provided are botanical or bacterial extracts and methods of treating skin and other tissues by applying certain botanical or bacterial extracts, such as from Acronychia acidula, Licaria vernicosa, Calendula officinalis, Trigonella foenum - graecum or Actimomyces bacteria, to the skin or other tissue. In particular, provided are methods of treating signs of skin aging, comprising topically applying to skin in need of treatment for signs of skin aging a composition comprising 3-(4-farnesyloxyphenyl)-propionic acid and/or its ethyl ester.
1. A method, comprising:
identifying skin with the presence of lines and wrinkles and/or loss of elasticity due to diminished synthesis of collagen or elastin,
topically applying to the skin a composition comprising a vehicle and a safe and effective amount of an agent that is 3-(4-farnesyloxyphenyl)-propionic acid and/or an ethyl ester thereof to elicit retinol-like bioactivity, and
wherein the application of the agent to the skin upregulates at least one of:
(a) cellular retinoic acid binding protein-II (CRAPB2),
(b) hyaluronic acid synthase 3 (HAS3),
(c) heparin-binding epidermal growth factor (HbEGF), or
(d) UDP-glucose ceramide glucosyltransferase (UGCG), on the order of a 0.1% retinol composition.
2. The method of claim 1 , wherein the composition is substantially free of retinol.
3. The method of claim 1 , wherein the application of the agent upregulates CRABP2 on the order of a 0.1% retinol composition.
4. The method of claim 3 , wherein the application of the agent upregulates CRABP2 by about 2-7 as compared to the vehicle alone.
5. The method of claim 4 , wherein the application of the agent upregulates CRABP2 by 3.38 to 9.06 as compared to the vehicle alone.
6. The method of claim 4 , wherein the application of the agent upregulates CRABP2 by about 2.96 or about 2.43 as compared to an untreated control.
7. The method of claim 1 , wherein the application of the agent upregulates HAS3 on the order of a 0.1% retinol composition.
8. The method of claim 7 , wherein the application of the agent upregulates HAS3 by about 1.33 to 5.22 as compared to an untreated control.
9. The method of claim 7 , wherein the application of the agent upregulates HAS3 by 1.33 to 3.87 or 1.76 to 5.22 as compared to an untreated control.
10. The method of claim 1 , wherein the application of the agent upregulates HbEGF on the order of a 0.1% retinol composition.
11. The method of claim 10 , wherein the application of the agent upregulates HbEGF by about 4.23 to 9.85 as compared to an untreated control.
12. The method of claim 10 , wherein the application of the agent upregulates HbEGF by 4.23 to 8.13 or 4.47 to 9.85 as compared to an untreated control.
13. The method of claim 1 , wherein the application of the agent upregulates UGCG on the order of a 0.1% retinol composition.
14. The method of claim 13 , wherein the application of the agent upregulates UGCG by about 1.27 to 7.93 as compared to an untreated control.
15. The method of claim 13 , wherein the application of the agent upregulates UGCG by 2.27 to 6.57 or 1.27 to 7.93 as compared to an untreated control.
16. The method of claim 1 , wherein the 3-(4-farnesyloxyphenyl)-propionic acid and/or the ethyl ester thereof is from an extract of Acronychia acidula.
17. The method of claim 1 , wherein the 3-(4-farnesyloxyphenyl)-propionic acid and/or the ethyl ester thereof is synthetically manufactured.
18. The method of claim 1 , wherein the skin is free of a skin lightening disorder.
19. A method, comprising:
identifying skin with the presence of lines and wrinkles and/or loss of elasticity due to diminished synthesis of collagen or elastin,
topically applying to the skin a composition comprising a vehicle and 3-(4-farnesyloxyphenyl)-propionic acid and/or an ethyl ester thereof to elicit retinol-like bioactivity, and
wherein the application of the 3-(4-farnesyloxyphenyl)-propionic acid and/or an ethyl ester thereof increases pro-collagen formation in the epidermal-dermal region on the order of a 0.1% retinol composition.
