  • Method of screening of substances for their effect on the expression of mediators of inflammation in a hair follicle
    Patent number: 5885766
    Abstract: An assay for determining whether a first substance is potentially suitable for use as an active agent in hair treating compositions is provided. This assay involves contacting a first substance having putative activity as an active agent for treating hair with plucked hair follicle contained in a culture medium and assaying for a second substance which is correlated to the potential efficacy of the first substance. This assay is particularly suitable for use in evaluating the potential efficacy of hair growth promoters, hair growth retardants, agents that affect hair color, agents that affect hair survival and agents that affect inflammation. This assay is especially suited for evaluating putative efficacy of agents for treatment and/or prevention of the inflammatory stages of alopecia. In particular, the compound to be quantitatively determined is a mediator of inflammation.

  • Use, in a composition, as cyclooxygenase activator and/or stabilizer, of at least one pyrimidine derivative sustituted at the 6th position and a cyclooxygenase substrate
    Patent number: 5756092
    Abstract: A composition and a method of treating alopecia or dermatological conditions with said composition are disclosed. The composition comprises at least one pyrimidine derivative substituted at the 6th position that activates and/or stabilizes cyclooxygenase, a pharmaceutically or cosmetically acceptable carrier and/or adjuvant and one of the following: a cyclooxygenase enzyme or a cyclooxygenase enzyme and at least one cyclooxygenase substrate comprising a polyunsaturated fatty acid having at least 20 carbon atoms. The composition is applied topically to the affected area or can be administered systemically.
