Cyclooxygenase(COX)-1 role in some diseases is increasingly studied. 3-(5-Chlorofuran-2-yl)-5-methyl-4-phenylisoxazole (P6), a highly selective cyclooxygenase-1 inhibitor, was used as a “lead” to design new isoxazoles (2a-m), differently selective towards COX-1. Those isoxazoles might be useful as novel theranostic agents and also to better clarify COX-1 role in the human physiology and diseases. 2a-m were prepared in fair to good yields developing suitable synthetic strategies. They were evaluated in vitro for their COX-inhibitory activity and selectivity. Structure-activity relationship studies of the novel set of diarylisoxazoles allowed to identify new key determinants for COX-1 selectivity, and to uncover compounds appropriate for a deep pharmacokinetic and pharmacodynamic investigation. 3-(5-Chlorofuran-2yl)-4- phenylisoxazol-5-amine (2f) was the most active compound of the series, its inhibitory activity was assessed in purified enzyme (COX-1 IC50 = 1.1 muM; COX-2 IC50 > 50 muM) and in the ovarian cancer cell line (OVCAR-3) expressing only COX-1 (IC50 = 0.58 muM). Furthermore, the high inhibitory potency of 2f was rationalized through docking simulations in terms of interactions with a crystallographic model of the COX-1 binding site. We found critical interactions between the inhibitor and constriction residues R120 and Y355 at the base of the active site, as well as with S530 at the top of the side pocket.

3,4-Diarylisoxazole analogues of valdecoxib [4-(5-methyl-3-phenylisoxazol- 4-yl)-benzensulfonamide], a selective cyclooxygenase-2 (COX-2) inhibitor, were synthesized by 1,3-dipolar cycloaddition of arylnitrile oxides to the enolate ion of phenylacetone regioselectively prepared in situ with lithium diisopropylamide at 0 C. The corresponding 3-aryl-5-methyl-4-phenyl- isoxazoles were easily generated by a dehydration/aromatization reaction under basic conditions of 3-aryl-5-hydroxy-5-methyl-4-phenyl-2-isoxazolines and further transformed into their benzenesulfonamide derivatives. The biochemical COX-1/COX-2 selectivity was evaluated in vitro by using the human whole blood assays of COX isozyme activity. Three compounds not bearing the sulfonamide group present in valdecoxib were selective COX-1 inhibitors.

Chemistry of Four-Membered Cyclic Nitrones. 3. Reaction with Nucleophilic Reagents and Stereospecific Conversion into 1-Hydroxyazetidines

Four-membered cyclic nitrones (1) react with a variety of nucleophiles (MeMgI, CN-, OH-, MeO-, and H-) by stereospecific addition to the C=N bond.Reaction of 1a with potassium cyanide and with methylmagnesium iodide yields the 1-hydroxyazetidines 2a and 2b, respectively.Reduction of 1b with lithium aluminum hydride and with sodium borohydride affords the 1-hydroxyazetidine derivatives 3 and 4, respectively.Sodium hydroxide in methanol-water reacts with 1a to give a mixture of two isomeric 5-hydroxyisoxazolidines 5a and 5b, but under similar reaction conditions 1b and 1c rearrange to the oximes 6 and 7.In acetic acid at room temperature 6a cyclizes to the 6H-1,2-oxazin-6-one derivative 8, whereas 6b yields 5-methyl-3,4-diphenylisoxazole (9) after being refluxed in acetic acid, probably by carbon monoxide elimination from the intermediate oxazin-6-one derivative.Reaction of 1a with sodium hydroxide for 2 min gives exclusively the 1-hydroxy-4-methoxyazetidine 13a, whereas prolonged reaction gives the isomeric azetidine 13b together with 5 (mixture of 5a and 5b in a ratio 4:1).Single-crystal X-ray analysis of 13b reveals that all three relatively bulky substituents at C-2, C-3, and C-4 are on the same face of the azetidine ring.Treatment of 13b with acetic acid at room temperature gives the 5-methoxyisoxazolidine 15.The 1-hydroxyazetidines 2-4 are oxidized with yellow mercury(II) oxide to the corresponding four-membered cyclic nitrones 1b, 16 and 17.

Selective COX-1 inhibition: A therapeutic target to be reconsidered

Since cyclooxygenase (COX) isozymes discovery, many papers and reviews have been published to describe the structural bases of COX inhibition, and to debate on the therapeutic and adverse effects of worldwide clinically used nonsteroidal anti-inflammatory drugs (NSAIDs), included COX-2 selective inhibitors (well known as Coxibs). COX-2 inhibition has been widely investigated, whereas the role of COX-1 in human pathophysiology is mostly not yet well ascertained. As time goes on, the cliche that the constitutively expressed isoform COX-1 is only involved in normal physiological functions, such as platelet aggregation, gastric mucosa protection and renal electrolyte homeostasis is going to be shattered. Low-dose aspirin, behaving as a preferential inhibitor of platelet COX-1, allowed to enlighten the role exerted by this isoenzyme in many mammalian cell types. This review would elucidate the most recent findings on selective COX-1 inhibition and their relevance to human pathology such as cancer, neuro-inflammation, cardioprotection, fever and pain. It would also focus on the design and development of new highly selective COX-1 inhibitors, useful tools in pharmacological studies aimed at gaining a deeper insight of the role of COX-1 in human health and disease. Among the traditional NSAIDs, other then aspirin and indomethacin, only few examples of selective COX-1 inhibitors (SC-560, FR122047, mofezolac, P6 and TFAP) have been so far identified. This review has also the scope to stimulate the development of novel drugs, which activity is COX-1 mediated.
