Protocol: Kinetic Aqueous Solubility Assay:

Pion's patented microSOL assay was used for kinetic solubility determination. In this assay, the classical saturation shake-flask solubility method was adapted as previously described by Avdeef et al., 2001. Test compounds were prepared in 10 mM DMSO stock and diluted to a final drug concentration of 150 microM in the aqueous solution (pH 7.4, 100 mM phosphate buffer). Samples were incubated at room temperature for 6 h and vacuum-filtered using Tecan Te-Vac to remove any precipitates. The concentration of the compound in the filtrate was measured via UV absorbance (lambda: 250-498 nm). The filtrate drug concentration was determined by comparing the fully solubilized reference plate which contained 17 microM of compound dissolved in spectroscopically pure n-propanol. All compounds were tested in duplicates. The kinetic solubility (microg/mL) of compounds was calculated using the microSOL Evolution software. The three experimental controls used were albendazole (low solubility), phenazopyridine (moderate solubility) and furosemide (high solubility) (1).

Comment: Compound Ranking:

1. Compounds are classified into different phenotypes according to the solubility observed. (A) Low: 0 - 10 ug / mL solubility; (B) Moderate / High: > 10 - 100 ug/ mL solubility. (C) N/A: solubility is not determined due to various reasons including precipitation from buffer, non-specific binding, etc.
2. Active compounds are compounds with Moderate / High phenotype (class = 0). Inactive compounds are those belonging to the Low category (class = 1).
3. PUBCHEM_ACTIVITY_SCORE is the whole number in Solubility (microg/mL) of the compound.

External ID: ADME-PAMPA1

Protocol: The stirring double-sink PAMPA method patented by pION Inc. (Billerica, MA) was employed to determine the permeability of compounds via PAMPA passive diffusion1,2. The PAMPA lipid membrane, which consisted of an artificial membrane of a proprietary lipid mixture and dodecane (Pion Inc.), was optimized to predict gastrointestinal tract (GIT) passive diffusion permeability. This membrane was immobilized on a plastic matrix of a 96 well "donor" filter plate placed below a 96 well "acceptor" plate. This artificial membrane mimicked the GIT membrane in the human body. Both "donor" and "acceptor" wells were buffered to pH 7.4. The test articles, stocked in 10 mM DMSO solutions, were diluted to 0.05 mM in aqueous buffer (pH 7.4) and the concentration of DMSO was 0.5% in the final solution. During the 30-minute permeation period at room temperature the test samples in the donor compartment were stirred using the Gutbox technology (Pion Inc.) to reduce the unstirred water layer. The test article concentrations in the "donor" and "acceptor" compartments were measured using a UV plate reader (Nano Quant, Infinite(R) 200 PRO, Tecan Inc., Mannedorf, Switzerland). Permeability calculations were performed using Pion Inc. software and were expressed in the units of 10-6cm/s.

Compound Ranking:
1. Phenotype compound classification is based on the Permeability values observed. Phenotype is "Low" if permeability is 0 - 10 (x 10^-6 cm/s); "Moderate" if permeability is 10 - 100 (x 10^-6 cm/s); and "High" if permeability > 100 (x 10^-6 cm/s). Compound has a phenotype "N/F" if Permeability is not found due to various reasons including but not limited to insolubility, non-specific binding, compound having high affinity to lipid, etc.

2. PUBCHEM_ACTIVITY_OUTCOME corresponds to Phenotype observed. PUBCHEM_ACTIVITY_OUTCOME is "active" for all compounds with "Moderate" to "High" Phenotype. PUBCHEM_ACTIVITY_OUTCOME is "inactive" for all compounds with "Low" Phenotype. For all compounds with phenotype N/F, PUBCHEM_ACTIVITY_OUTCOME is "inconclusive".

2. For all inactive compounds, with a ratio activity curve class of 4, PUBCHEM_ACTIVITY_SCORE is 0. For all active compounds, a score range was given for each curve class type given above. Active compounds have PUBCHEM_ACTIVITY_SCORE between 40 and 100. For a ratio activity curve class = 1.1, score = 80+abs((log_ac50+4.5)*inf_activity/20). For ratio.curve_class == 1.2 && abs(ratio.max_response) > 6*10, score = 60+abs((log_ac50+4.5)*inf_activity/20). For ratio.curve_class == 2.1 || ( ratio.curve_class==-2.2 && abs(ratio.max_response) > 6*10), score = 40+abs((log_ac50+4.5)*inf_activity/20). For ratio.curve_class == 1.2 || ratio.curve_class == 2.2, score = 20+abs((log_ac50+4.5)*inf_activity/20). Inconclusive compounds, with a donor curve class other than 4, have PUBCHEM_ACTIVITY_SCORE of 10. Inconclusive compounds also have PUBCHEM_ACTIVITY_SCORE between 1 and 39.

External ID: epac1-inhibitor-v

Protocol: Briefly, three uL of reagents (100 nM EPAC1, 250 nM RAP1B-BODIPY-GDP, 50 uM GDP) were dispensed into a 1536-well Greiner black solid-bottom medium binding assay plate. Controls and test compounds (23 nL) were transferred to the plate via a Kalypsys pin tool equipped with a 1536-pin array. The plates were centrifuged at 1,000 rpm for 15 seconds followed by 5 minute incubation at room temperature. The assay plates were read at 5 minute intervals for 30 minutes in the ViewLux plate reader using 480nm excitation and 540nm emission filters. The results were normalized to the agonist positive control ATA and DMSO.

Comment: Disclaimer:
Although all reasonable efforts have been made to ensure the accuracy and reliability of the data, caution should be exercised when interpreting the results as artifacts are possible from nonspecific effects such as assay signal interference. The curve fitting and activity calls presented here are based on the NCATS analysis methods.

Compound Ranking:
1. Compounds are first classified as having full titration curves, partial modulation, partial curve (weaker actives), single point activity (at highest concentration only), or inactive. For this assay, apparent inhibitors are ranked higher than compounds that showed apparent activation.
2. For all inactive compounds, with a ratio activity curve class of 4, PUBCHEM_ACTIVITY_SCORE is 0. For all active compounds, a score range was given for each curve class type given above. Active compounds have PUBCHEM_ACTIVITY_SCORE between 40 and 100. For a ratio activity curve class = -1.1, score = 80+abs((log_ac50+4.5)*inf_activity/20). For ratio.curve_class == -1.2 && abs(ratio.max_response) > 6*10, score = 60+abs((log_ac50+4.5)*inf_activity/20). For ratio.curve_class == -2.1 || ( ratio.curve_class==-2.2 && abs(ratio.max_response) > 6*10), score = 40+abs((log_ac50+4.5)*inf_activity/20). For ratio.curve_class == -1.2 || ratio.curve_class == -2.2, score = 20+abs((log_ac50+4.5)*inf_activity/20). Inconclusive compounds, with a donor curve class other than 4, have PUBCHEM_ACTIVITY_SCORE of 10. Inconclusive compounds have PUBCHEM_ACTIVITY_SCORE between 1 and 39.
