Application Protocols

No item-specific, validated application protocols are provided in the Product Data. The following general frameworks are commonly used for small-molecule GPCR antagonists and should be adapted and validated by the user.

• Calcium mobilization assay (general outline):

  1. Load cells expressing AVPR1A with a Ca2+ indicator dye.
  2. Preincubate with SR 49059 or vehicle for 15–30 min at 37°C.
  3. Stimulate with AVP; record real-time fluorescence. Analyze rightward shift and depression of maximal response vs. vehicle.

• IP1 accumulation or PLC activity assay:

  1. Preincubate cells with test compound.
  2. Challenge with AVP.
  3. Quantify IP1 or downstream markers per kit instructions; generate concentration–response curves.

• Binding assay (radioligand or BRET-based):

  1. Prepare membranes/cells expressing AVPR1A.
  2. Perform competition binding against a validated V1a tracer.
  3. Derive affinity estimates, ensuring proper controls and nonspecific binding determination.

Notes:

• Define and control final DMSO concentration.
• Use replicate wells and multiple independent experiments.
• Protect solutions and plates from light as indicated in the Product Data.

All protocols must be optimized for the specific cell line, receptor expression level, and instrumentation.

Biological Roles

Context from literature (not item-specific claims):

• SR 49059 is widely cited as a selective, nonpeptide antagonist of the vasopressin V1a receptor (AVPR1A), a class A GPCR that signals predominantly via Gq/11, phospholipase C activation, IP3 generation, and intracellular Ca2+ mobilization.

Applications enabled by V1a antagonism:

• Dissecting AVPR1A function in vascular smooth muscle, liver, CNS, and other tissues expressing V1a, by blocking endogenous arginine vasopressin (AVP) responses.
• Establishing receptor selectivity in pharmacology panels, differentiating V1a from V1b (AVPR1B) and V2 (AVPR2) mediated pathways.
• Mapping downstream signaling (e.g., Ca2+ flux, ERK phosphorylation) and transcriptional responses to V1a blockade in cells or tissue preparations.

Experimental considerations:

• Conduct concentration–response studies in the presence of AVP to determine functional antagonism (e.g., rightward shift in agonist curves). Report vehicle composition and temperature, as these influence GPCR assay results.
• Consider receptor reserve and expression level: apparent potency can vary across systems. Use radioligand binding or BRET-based binding where available to complement functional readouts.
• Off-target risk management: Incorporate secondary pharmacology panels or control ligands to ensure observed effects are V1a-specific for the system under study.

All uses are for research only. No claims are made regarding therapeutic properties or clinical performance.

Buffer Applications

This item is a bioactive small-molecule ligand, not a buffering agent. It does not define or maintain pH and is not used to formulate classical biological buffers.

Practical note:

• When used in biological assays, prepare SR 49059 working solutions in your existing buffer system (e.g., HEPES, PBS, assay-specific media) using an appropriate co-solvent such as DMSO. Validate that the final solvent percentage does not perturb pH or assay performance.

For buffer recipes and pH ranges, refer to standard buffering agents rather than this ligand.

Green Alternatives

As a finished bioactive ligand, SR 49059 is not typically interchangeable with “green alternative” chemicals in the way solvents or common reagents are. However, greener choices can be made around its use:

• Solvent considerations (general):

  • Prefer the minimum effective DMSO percentage in working solutions; evaluate ethanol or aqueous cosolvent systems when compatible with the assay to reduce DMSO usage.
  • Use micro-scale assay formats to minimize chemical and solvent consumption.

• Process and waste minimization:

  • Consolidate screening plates and replicate runs to reduce waste.
  • Implement solvent recycling for analytical development where feasible.

• Alternatives at the biology level (literature context):

  • If the scientific objective is “functional V1a antagonism,” alternative tool compounds with comparable selectivity profiles may be considered to confirm findings via chemotype diversity. Selection should be driven by potency, selectivity, solubility, and safety data in the literature, not by environmental attributes alone.

There are no direct “greener chemical substitutes” for SR 49059 itself without changing the pharmacological probe. Optimize handling, solvent choice, and experimental design to improve sustainability.

Pharmaceutical Uses

This product is provided strictly for research use only.

Context (general, non-clinical):

• SR 49059 is recognized in the literature as a pharmacological tool compound for the vasopressin V1a receptor. In pharmaceutical R&D settings, such ligands may serve as reference standards in assay development, target validation, SAR benchmarking, and DMPK method development.

Formulation/analytical considerations (general):

• Reference standards are often stored as dry material or DMSO concentrates and used to qualify bioassays (e.g., potency controls), LC–MS quantitation methods, or receptor binding formats.
• Excipient status or pharmacopeial monographs: Not specified for this item; verify compendial listing if regulated development is intended (this listing is research-grade Moligand).

No therapeutic, diagnostic, or clinical claims are made for this item. Any use beyond laboratory research must be independently validated and fall under appropriate regulatory oversight.

Physical Properties

Item-specific physicochemical specifications are not supplied in the Product Data for this listing.

• Appearance: Not specified for this item; refer to CoA/Spec Sheet.
• Molecular weight: Not specified for this item; refer to CoA/Spec Sheet.
• Molecular formula: Not specified for this item; refer to CoA/Spec Sheet.
• Melting point, boiling point, density, refractive index, pKa, logP/logD, UV cutoff: Not specified for this item; refer to CoA/Spec Sheet.
• Solubility: Not specified for this item; refer to CoA/Spec Sheet.

General literature guidance for small-molecule GPCR ligands (context, not item-specific specifications):

• Many V1a antagonists are moderately lipophilic and are commonly handled as DMSO stock solutions for in vitro assays; aqueous solubility can be formulation-dependent.
• If analytical characterization is needed, typical panels include HPLC purity, HRMS, 1H/13C NMR, and water content by Karl Fischer; obtain values from the item’s CoA.

Practical notes:

• Before preparing solutions, consult the specific CoA/SDS for this item to determine actual solubility limits, stability in aqueous buffers, and any light sensitivity beyond the storage note provided.
• For spectroscopic or bioassay method development, verify extinction coefficients and assay-compatible solvent systems empirically for this exact lot/item.

Quality and Grades

• Grade/Purity (from Product Data): Moligand™.

About Moligand (general description of the grade/series):

• Moligand is Aladdin’s line for research-grade small-molecule ligands intended for in vitro/in vivo exploratory research, screening, target validation, and pharmacology method development. It emphasizes identity confirmation and appropriate purity for biochemical and cell-based assays.

What this means for the user:

• For GLP/GMP or regulatory studies, this research-grade material may not be suitable; consider sourcing to the required standard and verify compendial status if applicable.

Reaction and Applications

This product is supplied as a bioactive research ligand rather than a synthetic reagent.

• Synthetic reaction use: SR 49059 is not typically employed as a reagent, catalyst, or building block in preparative organic synthesis. Accordingly, there are no standard reaction families or named transformations in which it serves as a substrate.

• Research applications (general, literature-based context):

  • Used as a selective antagonist tool compound to interrogate vasopressin V1a (AVPR1A) signaling in biochemical and cellular assays.
  • Supports studies of GPCR-mediated Gq/PLC/IP3–Ca2+ pathways, receptor pharmacology, and target validation where V1a antagonism is required.

• Primary solvent: DMSO is commonly used to prepare concentrated stocks (e.g., 10–50 mM) due to broad solubilizing power for lipophilic ligands. Confirm maximum solubility for this item from the CoA or by a small-scale test.
• Working solutions: Dilute DMSO stocks into assay buffers or media, keeping final DMSO typically ≤0.1–0.5% v/v to minimize vehicle effects; verify tolerance for your system.
• Alternative solvents: DMF or ethanol may be suitable for some assays or analytical preparations; assess compatibility with your biology/analytics.
• Aqueous systems: If aqueous solubility is limited, consider co-solvent strategies, cyclodextrin inclusion, or surfactant-assisted delivery (ensuring biological compatibility and appropriate controls).

Comparison (general considerations, not item-specific):

• DMSO: highest solvency; potential cytotoxicity at higher %.
• Ethanol: easier evaporation, but lower solvency for very lipophilic compounds.
• PBS/aqueous buffer: best biological compatibility but may require co-solvents.

Always confirm actual solubility, stability, and adsorption to plastics/glass for this specific item/lot under your conditions.

Storage and Reconstitution

• Storage conditions (from Product Data): Store at −20°C, protected from light. Shipment: ice chest with ice pads.

• Reconstitution (general guidance for small-molecule ligands; not item-specific specifications):

  • Use dry, oxygen-free DMSO to prepare a concentrated stock solution. If water or buffer stocks are required, determine solubility empirically and consider co-solvents.
  • Filter sterilize through a low-protein-binding 0.2 µm membrane if sterility is required for cell assays (confirm no adsorption loss).
  • Aliquot into amber or foil-wrapped microtubes to avoid repeated freeze–thaw and light exposure.

• Handling and stability:

  • Allow vials to equilibrate to room temperature in a desiccated environment before opening to prevent moisture condensation.
  • Record preparation date, solvent, and concentration on each aliquot. Monitor for precipitation or color change.

• Solution storage (general):

  • DMSO stocks are commonly stored at −20°C (or below) protected from light. Avoid multiple freeze–thaw cycles; thaw on ice when possible.

Item-specific parameters such as exact solubility, hygroscopicity, and solution stability are not specified for this item; refer to the lot-specific CoA and SDS for definitive guidance.

Exact atom connectivity for this catalog item is not specified here and should be confirmed from the supplier’s CoA/structure file before computational or analytical work.

Synthetic Utility

SR 49059 is supplied as a bioactive, target-directed small molecule and is not typically used as a synthetic intermediate or reagent.

• Functional group reactivity: Not characterized here for preparative chemistry purposes; refer to CoA/SDS if chemical modification is contemplated.
• Derivatization: While literature strategies sometimes derivatize tool compounds for probes (e.g., biotinylation, photoaffinity tags), such work requires full structural confirmation, protection of key pharmacophores, and rigorous SAR verification. No item-specific guidance is provided.

If your objective is chemical synthesis or conjugation:

• Obtain definitive structure files (SMILES/SDF) and confirm reactive handles.
• Perform small-scale feasibility studies to ensure biological activity is retained after modification.

For most users, the primary value of this product lies in its role as a selective receptor antagonist in biological assays rather than as a building block.

Target Specificity

Target information from literature (contextual; not item-specific testing data):

• Primary target: Vasopressin V1a receptor (AVPR1A), a Gq/11-coupled GPCR activated by arginine vasopressin (AVP).
• Pharmacological profile: Reported as a selective antagonist for V1a over V1b (AVPR1B) and V2 (AVPR2) in published studies. Exact Ki/IC50 values and selectivity ratios are system- and assay-dependent and are not provided for this catalog item.

Implications for experimental design:

• Use AVP as an agonist control to demonstrate competitive/functional antagonism and to distinguish V1a from V2/V1b responses.
• Incorporate secondary assays or orthogonal readouts (e.g., Ca2+ mobilization vs. ERK phosphorylation) to confirm on-target effects.
• If target engagement in cells or tissues is required, consider CETSA, NanoBRET, or radioligand binding approaches using validated tracers.

Item-specific bioactivity testing, clone/isotype, species cross-reactivity, and epitope data are not applicable, as this is a small molecule and not an antibody or biologic. For verified potency/selectivity values, consult primary literature or the lot-specific CoA if provided.
