- 5-lipoxygenase is an enzyme that is expressed exclusively in white cells of myeloid lineage. It is an oitosolic enzyme that, when the cell is activated by an agent that generates a cytosolic Ca pulse, translocates by binding to a membrane protein called FLAP (five lipoxygenase activating protein).
- FLAP five lipoxygenase activating protein
- the first reaction that it catalyzes is the transformation of AA into 5(S)-hydroperoxy-(E,Z,Z,Z)-6,9,11,14-eicosatetraenoic acid, abbreviated 5-HPETE.
- 5-HPETE 5(S)-hydroperoxy-(E,Z,Z,Z)-6,9,11,14-eicosatetraenoic acid
- hydroperoxide is converted catalytically by 5-LO into an unstable epoxide: the so-called leukotriene A 4 or LTA 4 .
- Part of the 5-HPETE is reduced to the corresponding hydroxide 5-HETE, through the action of
- Leukotriene LTA 4 is the precursor of the transformations that lead to all other leukotrienes. Thus, since there are no alternative routes for LTA biosynthesis 4 , inhibition of 5-LO leads to the blocking of the biosynthesis of all
- LTA 4 is transformed into leukotriene B 4 or LTB 4 , which occurs in the
- LTB 4 is w-oxidized, giving rise to 20-(OH)-LTB 4 .
- LTA 4 also undergoes non-enzymatic transformations to
- the major products are those indicated in Fig. 1 with the usual abbreviations, that is, the two 6-trans-LTB 4 acids and the two 5,6-DiHETE acids.
- the 5-LO inhibitory value of the Bobel-24 product is one of the highest ever reported. To make sure that this spectacular result is not an artifact, it has been verified that the release of lactate dehydrogenase (LDH) into the incubation medium is not attributable to lysis.

- the derivatives of 2,4-disubstituted phenols of the present invention are anti-herpetic agents in vivo, since they eliminate the symptoms in patients suffering from different modalities of herpes simplex (genital herpes, orolabial herpes, recurrent herpes), as well as in patients afflicted with herpes zoster, without recurrence after abandoning treatment.
- the products are active both intramuscularly and topically, the former being preferred. Although their mechanism of action is unknown, it is almost certain that it is due to their inhibitory activity against 5-LO, since in the tests carried out they have been found to be inactive in vitro. - 18 -

- 20-OH-LTB 4 and 5-HETE their concentration decreased approximately linearly with the inhibitory drug concentration.
- the slopes of these lines were much greater in the case of Bobel-24 than in the other two.
- the drug Bobel-24 showed surprisingly high 5-LO inhibitory activity, much higher than either benoxaprofen or ketoconazole.
- IC 5Q values micromolar concentration of drug that inhibits 50% of the amount of AA transformed by 5-LO
- IC 5Q * 10 ⁇ 2 for Bobel-24
- Ic so 92 ⁇ 19 for benoxaprofen
- IC 5Q 102124 for ketoconazole.
- a Bobel-24 concentration of approximately one tenth of the necessary concentration of benoxaprofen or ketoconazole is sufficient.

There was therefore a clear and generalized disappearance of the symptoms.
- the case of genital herpes classified as "regular" results corresponds to a very obese and diabetic woman in whom, although there was improvement, there was a recurrence.
- An independent assay for "in vitro" antiviral activity was negative.
- Example 7 "In vivo" activity in cases of herpes zoster.
- a total of 21 patients with clear symptoms of herpes zoster were treated with 15 mg/day of Bobel-24, by intramuscular injection, for one month.
- the results regarding the disappearance of the symptoms were the following: excellent in 18 cases, good in 2 cases, and fair in 1 case.
- the product precipitates spontaneously from the medium, it is filtered off. If it does not, it is caused to precipitate by adding water or, alternatively, add water (30 parts by volume) and extract with dichloromethane.
- the crude solid or organic extract is washed with 5% aqueous sodium bisulfite solution, and then with water.
- the organic extract is dried over magnesium sulfate, the solvent is removed under vacuum and the resulting solid or oil is dried.
- the crude contains products with different degrees of iodination, which can be separated by chromatography on silica gel, with hexane:diethyl ether 5:1 as eluent.
- Example 9 Preparation of injectables.

- Example 10 Preparation of capsules. Using magnesium stearate as a lubricant and lactose as a diluent, hard gelatin capsules were prepared. - 26 -
- Example 11 Preparation of shampoo. Due to the insolubility of Bobel-24 in an aqueous medium, it was previously solubilized in a 50% lysine solution. A sulfonated anionic detergent containing 10-15% tegobetaine, 20-30% texapon N-40, and water was used as the foaming agent. A 2% shampoo was prepared with the following composition: 2.0 g Bobel-24, 12.0 ml 50% aqueous lysine solution, 48.0 ml water, 40.0 ml anionic sulfonated detergent.
- Example 12 Preparation of eye drops.

At the beginning and at the end of treatment, blood, synovial fluid, and urine samples were taken in order to perform the following tests: Synovial fluid analysis (cytology, cytokines 1, 6, 8, and TNF), LTB4, LTC4, PGE2; blood count and leukocyte formula; routine serum biochemistry parameters; urinary sediment; Rose-Aaler test; - 27 -
- Table 4 Evolution of the dogs after 45 days of treatment with 4 mg/kg.day of Bobel-24 orally.
- Example 14 Clinical trial in canine arthritis. After diagnosis, each animal was treated with Bobel-24 capsules for 15 days. At the beginning and at the end of the treatment, samples of blood, synovial fluid and urine were taken, in order to carry out the same tests as in Example 13, using the same notation for the clinical evolution. The results obtained are shown -28
- Table 5 Evolution of the dogs after 15 days of treatment with 2 mg/kg.day of Bobel-24 orally.
- Example 15 Clinical trial in canine seborrheic dermatitis.
- the treated animals were diagnosed as having seborrheic dermatitis, and the diagnosis had been confirmed by biopsy.
- the treatment consisted of the application of a weekly bath with 2% Bobel-24 shampoo, and evaluation of the treatment after fifteen days.
- the effectiveness of the treatment was carried out by evaluating the following therapeutic objectives: removal of scales and scabs, reduction of gra ⁇ itude, reduction of seborrheic odor, relief of pruritus, anti-inflammatory effect.
- (+++) very good response, clinical cure
- (+) moderate response, improvement
- (-) negative response or no apparent improvement.
- the treatment is shown to be one of the most effective topical treatments, the absence of adverse or secondary effects being remarkable, such as skin or mucous membrane irritation, and unpleasant odors.
- Table 6 Evolution of dogs diagnosed with seborrheic dermatitis, after 15 days of topical treatment with a weekly bath of Bobel-24 to 2- shampoo,
