Example 17a: (1s,3S,12R,15R,18s)-3-fluoro-12-methyl-8,17-dioxa-11-azaspiro[morpholine-3,14-tetracyclo[16.2.2.0.SUP.2,7.0.0.SUP.11,15.]docosane]-2,4,6-triene-5,10-dione

Example 17b: (1s,3R,12R,15S, 18s)-3-fluoro-12-methyl-8,17-dioxa-11-azaspiro[morpholine-3,14-tetracyclo[16.2.2.0.SUP.2,7.0.0.SUP.11,15.]docosane]-2,4,6-triene-5,10-dione

[0428] To a stirred solution of HATU (201 mg, 0.529 mmol) and DIPEA (182 L, 1.04 mmol) in acetonitrile (24.3 mL) was added Intermediate 68 (250 mg) in DMF (2.4 mL) over 2h using a syringe pump. The resulting solution was stirred for one hour. The reaction mixture was concentrated in vacuo to afford the crude material. The mixture was diluted in water and extracted with DCM (35 mL) The combined organic extracts were dried (MgSO.sub.4), filtered and concentrated to give a solid residue. The crude material was purified by basic reverse phase column chromatography (15-45% acetonitrile in water (0.1% ammonia)) to afford the title compounds (Peak 1, 8.6 mg) as a white solid and (Peak 2, 11.3 mg) as a white solid.

The reaction mixture was stirred at 0 C. for 2 hours and ice and saturated aqueous NaHCO.sub.3were poured into the mixture. The reaction mixture was extracted with DCM (210 mL). The combined organic phases were washed with brine, dried over MgSO.sub.4 and concentrated in vacuo to afford the crude. The crude material was purified by basic reverse phase column chromatography (15-45% acetonitrile in water (0.1% ammonia)) to afford the title compounds (Peak 1, 3.9 mg and Peak 2, 3.8 mg).

Ip-1 Accumulation Assay

[0774] The accumulation of Inositol-1 Monophosphate (IP-1) was measured using IP-One HTRF Terbium cryptate based assay (Cisbio) in human recombinant OX1 (hOX1) and at OX2 (hOX2) receptors expressed in CHO cells (DiscoverX) according to the manufacturer's instructions for cells tested in suspension.

[0775] hOX1-CHO and hOX2-CHO cells were seeded into white 384-well plates at a density of 20,000 cells/well in Hank's Balanced Salt Solution (HBSS) containing 20 mM HEPES pH 7.4, 50 mM, LiCl and 0.1% and Bovine Serum Albumin (BSA).

[0776] Compounds of disclosure were tested in an 11 points concentration response curve (CRC) serially diluted in neat DMSO at 200 fold concentrations and added by Echo acoustic liquid handling (Labcyte) to the cells (0.5% DMSO final in the assay). After 60 min of incubation at 37 C. detection reagents, IP1-d2 tracer and anti-IP1-cryptate were diluted in lysis buffer according to the manufacturer's descriptions and added to the cells.

[0777] Following 60 min incubation at room temperature, time-resolved fluorescence (HTRF) was measured at 615 nm and 665 nm by Envision Multilabel reader (Perkin Elmer) and the HTRF ratio (A665/A61510.sup.4) was calculated.

[0778] The IP-1 accumulation response was expressed as percentage of the maximal OX-A response.

[0779] Curve fitting and EC.sub.50 estimations were carried out using a four-parameter logistic model using XLfit Software. Mean data of EC.sub.50 are calculated from at least two independent experiments performed in duplicates

[0780] Category A corresponds to compounds displaying an IC50<100 nM, Category B between 100 nM and 1,000 nM, Category C between 1,000 nM and 10,000 nM and Category D above 10,000 nM
