A newly developed synthesis of a NO-releasing prodrug of rofecoxib is described. The highly productive process consists of five chemical steps and produces prodrug 1 in an overall 64% yield from commercially available 3-phenyl-2-propyn-1-ol (4). The synthesis is highlighted by the carbometalation reaction of propargyl alcohol 4 to generate the tetrasubstituted olefin core, sulfone acid 2. Additionally, two alternate end-game strategies to prepare NO-COXIB I from this intermediate were explored and developed: (1) a convergent synthesis where a bromonitrate side chain is introduced in one step and (2) a two-step sequence that first installs the requisite six-carbon ester side chain followed by chemoselective nitration.

The invention encompasses a novel process for making compounds of Formula I
which are prodrugs of cyclooxygenase-2 selective inhibitors that convert in vivo to diaryl-2-(5H)-furanones and also liberate nitric oxide in vivo. As such, the compounds made by the present invention may be co-dosed with low-dose aspirin to treat chronic cyclooxygenase-2 mediated diseases or conditions, effectively reduce the risk of thrombotic cardiovascular events and potentially renal side effects and at the same time reduce the risk of GI ulceration or bleeding. The present invention describes an efficient and economical process for the preparation of 2,3-disubstituted (2Z)-4-acetoxybut-2-enoate derivatives that is useful for the production of kilogram quantities of material for preclinical and clinical use.

Disclosed herein are compositions and compounds that combine an inhibitor of
5
-lipoxygenase activating protein (FLAP) and a modulator of NO levels in a mammal. The NO modulator can be an agent that induces the production of NO in a mammal, or can be an agent that itself produces NO in the mammal. Further disclosed herein are strategies for synthesizing such compounds, and methods for testing whether the combination compounds and compositions provide a desired benefit. Also disclosed herein are pharmaceutical compositions and formulations that combine a FLAP inhibitor and an NO modulator. Further described herein are methods for using such compositions and compounds for the treatment of diseases, conditions, and disorders in a mammal, including a human. Such treatment methods include the separate administration of a FLAP inhibitor and a NO modulator to the mammal, and the simultaneous administration of a FLAP inhibitor and a NO modulator to the mammal.
The first series of nitric oxide donating derivatives of evodiamine were designed and prepared. NO releasing ability of all target derivatives was evaluated in BGC-823, Bel-7402 and L-02 cells. The cytotoxicity was evaluated against three human tumor cell lines (Bel-7402, A549 and BGC-823) and normal human liver cells L-02. The nitrate derivatives 11a and 11b only exhibited moderate activity and furoxan-based derivatives 13a-c, 14a and 14b showed promising activity. 13c showed good cytotoxic selectivity between tumor and normal liver cells and was further investigated for its apoptotic properties on human hepatocarcinoma Bel-7402 cells. The molecular mode of action revealed that 13c caused cell-cycle arrest at S phase and induced apoptosis in Bel-7402 cells through mitochondria-related caspase-dependent pathways.
