EXAMPLE

(51) Without further elaboration, it is believed that one skilled in the art can, based on the above description, utilize the present disclosure to its fullest extent. The following specific examples, i.e., EXAMPLES 1-26, are therefore to be construed as merely illustrative, and not limitative of the remainder of the disclosure in any way whatsoever. All publications cited herein are incorporated by reference in their entirety.

(52) Among the specific examples, EXAMPLES 1-24 set forth the procedures for preparing certain intermediates and 390 exemplary compounds of formula (I), as well as the analytical data for the compounds thus prepared; and EXAMPLES 25 and 26 set forth the protocols for testing these compounds.

(53) Described below are the procedures used to synthesize the exemplary compounds of the present disclosure.

(54) Unless otherwise stated, all starting materials used were commercially available and used as supplied. Reactions requiring anhydrous conditions were performed in flame-dried glassware and cooled under an argon or nitrogen atmosphere. Unless otherwise stated, reactions were carried out under argon or nitrogen and monitored by analytical thin-layer chromatography performed on glass-backed plates (5 cm_10 cm) precoated with silica gel 60 F254 as supplied by Merck. Visualization of the resulting chromatograms was done by looking under an ultraviolet lamp (λ=254 nm), followed by dipping in an nBuOH solution of Ninhydrin (0.3% w/v) containing acetic acid (3% v/v) or ethanol solution of phosphomolybdic acid (2.5% w/v) and carring by heat gun. Solvents for reactions were dried under an argon or nitrogen atmosphere prior to use as follows. THF, Toluene, and DCM were dried by the column of Dried molecular Sieve 5A (LC technology solution Inc). DMF dried by calcium hydride or anhydrous is commercial available. Flash chromatography was used routinely for purification and separation of product mixtures using RediSep Rf Silica Gel Disposable Flash Columns, Gold® 20-40/40-60 microns silica gel and Reusable RediSep Rf Gold® C18 Reversed Phase columns, 20-40 microns supplied by RediSep. Eluent systems are given in volume/volume concentrations. .sup.13C and .sup.1H NMR spectra were recorded on Bruker AVIII (400 MHz). Chloroform-d or dimethyl sulfoxido-d6 and CDsOD was used as the solvent and TMS (δ 0.00 ppm) as an internal standard. Chemical shift values are reported in ppm relative to the TMS in delta (δ) units. Multiplicities are recorded as s (singlet), br s (broad singlet), d (doublet), t (triplet), q (quartet), dd (doublet of doublet), dt (doublet of triplet), m (multiplet). Coupling constants (J) are expressed in Hz. Electrospray mass spectra (ESMS) were recorded using a Thermo LTQ XL mass spectrometer. Spectral data were recorded as m/z values.

(55) In the preparation of compounds of the present invention, protection of remote functionality (e.g., primary or secondary amine) of intermediates may be necessary. The need for such protection may vary depending on the nature of the remote functionality and the conditions of the preparation methods. Suitable amino protecting groups (NHPg) include, for example, acetyl, trifluoroacetyl, tbutoxycarbonyl (BOC), 9-fluorenylmethyleneoxycarbonyl (Fmoc) and benzyloxycarbonyl (CBz). Similarly, a “hydroxyl protecting group” refers to a substituent of a hydroxy group that blocks or protects the hydroxy functionality. Suitable hydroxyl protecting groups (OPg) include, for example, allyl, acetyl, silyl, benzyl, paramethoxy benzyl, trityl, and the like. The need for such protection is readily determined by one skilled in the art.

Example 25: Evaluation of Compounds of Formula (I) in In Vitro Assays

(919) Glucagon cAMP Inhibition Assay

(920) Downstream secondary messenger cAMP induced by glucagon was detected by Cisbio cAMP Dynamic 2 kit. Testing compounds were each prepared as a dimethyl sulfoxide (DMSO) solution at the concentration of 10 mM. To evaluate the potency of compounds in inhibiting the cAMP production, glucagon receptor (GCGR) overexpressed CHO-K1 cells or human primary hepatocytes were treated with compounds with a serial dilution. The cells were re-suspended in Hank's Balanced Salt solution (HBSS) contained 0.1% (w/v) bovine serum albumin and 800 nM 3-isobutyl-1-methylxanthine (IBMX) and seeded into low volume, 384 wells white plate. The diluted compounds were then added into the plate for 30 minutes pre-incubation where the final DMSO concentration was 1%. The cells were stimulated with glucagon at the concentration equaled to EC50 (an indicium of the concentration of a drug that gives half-maximal response) for 30 minutes at room temperature. After incubation, lysis buffer contain cAMP antibody and fluorescence acceptor were added into each well for additional 60 minutes incubation. Results were recorded by Molecular Devices SpectraMax Paradigm with the HTRF Detection Cartridges and the IC.sub.50 value of each compound in inhibiting the cAMP production was calculated with non-linear regression based on the amount of cAMP production.

(921) I.sup.125-Glucagon Binding Assay

(922) The binding affinity of each compound was evaluated by a competition assay with I.sup.125-glucagon. GCGR membrane fractions were obtained from GCGR overexpressed CHO-K1 cells as a stock of 1 mg/ml concentration. To evaluate the IC.sub.50 of compounds binding to GCGR, GCGR membrane fractions were treated with compounds with a serial dilution. The membrane fractions were diluted to 7.5 microgram per well in 70 microliter assay buffer contained 50 mM Tris pH 7.4 and 0.5% (w/v) bovine serum albumin and added into 96 wells plate. The membrane fractions were then mixed with 10 microliter diluted compounds. After 5 minutes pre-incubation, 20 microliter I.sup.125 labeled glucagon (Perkin Elmer) was added into each well at the final concentration of 0.0625 nM. The assay mixtures were incubated at 25° C. for 30 minutes and then transferred onto the Millipore MultiScreen GF/B Plate coated with 0.5% (w/v) Polyethyleneimine. The filter plate was washed with wash buffer contained 50 mM Tris pH 7.4 for 2 times, 300 microliter each time. The residual isotope was detected by Hidex CHAMELEON V micro-beta counter and the IC.sub.50 value of each compound binding to GCGR was calculated with non-linear regression.

(923) The compounds prepared in EXAMPLES 1-24 were tested in two in vitro assays described below. The results are shown in Tables 1-24 shown below.
