  • Include positive/negative controls and counterscreens to identify assay interference.
• Cell-based assays
  • Confirm compound compatibility with serum and plasticware; pre-wet tips and use low-bind plates to reduce adsorption.
  • Titrate to determine cellular potency and cytotoxicity; include vehicle controls.
• Data quality
  • Monitor for aggregation (e.g., detergent sensitivity, DLS) and optical interference (compound fluorescence/absorbance).

Biological Roles

Item-specific biological characterization is not provided in the Product Data.

General, literature-oriented context (not a medical claim, not item-specific)

• DMP-543 has been cited in the literature as a bioactive small molecule used in neuropharmacology research. Researchers have explored related chemotypes to modulate neuronal ion channel activity and neurotransmission in vitro. For precise target annotation, binding constants, and selectivity profiles for DMP‑543, consult primary publications associated with CAS 160588-45-4 and the PubChem record (CID: 9887884).
• Typical research uses for comparable ligands include target engagement studies, electrophysiological recordings, and pathway interrogation in cell lines or primary neurons.

Important

• For this catalog item, no target specificity, potency, or selectivity data are provided. Verify suitability in your system through pilot assays and orthogonal confirmation methods (e.g., electrophysiology, radioligand binding, or proteomics-based target deconvolution as applicable).

Buffer Applications

This product is a discrete small-molecule ligand rather than a buffering agent. It is not typically used to prepare biological buffers or to control pH.

Practical note (assay handling)

• When dosing into buffered systems, prepare concentrated DMSO stocks and dilute into the desired buffer (e.g., HBSS, PBS, HEPES-buffered media) maintaining a consistent final DMSO percentage across all conditions (commonly ≤0.5–1% v/v). Include vehicle controls to account for co-solvent effects.

Green Alternatives

Green chemistry considerations are generally applied to solvents and bulk reagents rather than to discrete screening compounds like DMP-543. As such, there are no direct “greener substitutes” for the active molecule itself.

However, you can enhance the sustainability profile of your workflows by focusing on the surrounding process:

• Solvent choices for handling and assays
  • Prefer lower-toxicity solvents (e.g., ethanol, water with minimal DMSO) when compatible with assay performance.
  • Minimize DMSO volumes and adopt microplate formats that reduce solvent consumption.
• Procurement and use
  • Use concentrated stocks and miniaturized assay volumes (uHTS) to limit material and solvent waste.
  • Plan experiments to minimize repeated freeze–thaw cycles and associated disposables.
• Waste management
  • Segregate halogenated vs non-halogenated organic waste; collect DMSO-containing waste per institutional policy.

Trade-offs

• Greener co-solvents may reduce solubility or alter assay readouts; always balance EHS benefits with data quality requirements and validate replacements empirically.

Pharmaceutical Uses

• Regulatory/compendial status: Not pharmacopeial; supplied strictly for research use only.
• Typical role in R&D (general): As a reference or screening compound within discovery programs (e.g., target validation, lead identification). It is not intended for human or veterinary use, diagnostic procedures, or as an excipient.
• Formulation notes for research (not for human use):
  • Prepare assay-ready solutions in DMSO and dilute into compatible media immediately before use to minimize precipitation and degradation.
  • For in vivo research in animals (if permitted by your institution), formulation development must be performed de novo with appropriate controls; no guidance is provided here for dose or vehicle—consult your IACUC and institutional policies.

Reaction & Applications

This product is supplied as a research small molecule (Moligand™) and is not typically used as a synthetic reagent or solvent. Consequently, classical synthetic reaction guidance (e.g., coupling partners, bases, catalysts) is not generally applicable.

Research applications (general, literature-based context; not item-specific)

• Small-molecule screening: Suitable for inclusion in biochemical or cell-based assay panels to probe target engagement, pathway modulation, or phenotypic outcomes.
• SAR development: Can serve as a reference chemotype within medicinal chemistry campaigns for structure–activity relationship comparisons, contingent on your internal benchmarks.
• Biophysical profiling: Evaluate ligandability using SPR, DSF, MST, or thermal shift assays, with attention to compound aggregation and optical interference controls.

Practical considerations

• Prepare fresh DMSO stocks for screening and minimize freeze–thaw cycles.
• Include counter-screens to detect assay artifacts (fluorescence interference, redox cycling, or colloidal aggregation); use detergents and dynamic light scattering controls as appropriate.

Reaction Conditions

Not typically applicable. DMP-543 is supplied as a research small molecule rather than a reagent or substrate for synthetic transformations.

General handling conditions for assay use (not item-specific)

• Stock preparation: 10–50 mM in anhydrous DMSO; store aliquots at ultra‑low temperature to avoid repeated freeze–thaw.
• Working solutions: Dilute into assay buffer or culture media to the desired concentration while keeping DMSO ≤0.5–1% v/v (or per your assay tolerance).
• Light/oxidation sensitivity: When in doubt, protect from light and air; use amber vials and inert headspace for long-term storage of solutions.

Solvent Selection

Because item-specific solubility data are not provided, select solvents based on general best practices for small-molecule screening and your assay modality:

• Primary stock solvent (general practice, not item-specific):
  • Anhydrous DMSO is the standard for 10–50 mM master stocks due to broad solvency and assay compatibility at ≤0.5–1% v/v in biological media.
• Secondary options (if compatible; verify experimentally):
  • DMF or NMP for challenging chemotypes in biophysical assays (consider cytotoxicity on dilution).
  • Ethanol or isopropanol for certain biochemical assays where DMSO is undesirable; evaluate solubility and enzyme tolerance.
• Aqueous media
  • Direct dissolution in aqueous buffers is often limited for hydrophobic discovery compounds; co-solvent strategies (0.1–1% DMSO + nonionic surfactant like 0.01% Tween-20) may improve delivery. Validate that additives do not interfere with readouts.
• Practical tips
  • Warm gently (room temperature) and vortex/sonicate briefly to aid dissolution; avoid prolonged heating.
  • Filter stock solutions (PTFE or PVDF, 0.22 µm) if particulates persist; confirm no analyte loss to membrane.
  • Document final co-solvent concentration in assays to ensure reproducibility.

Storage & Reconstitution

• Storage conditions (item-specific from Product Data): Store at -80°C.
• Shipping (item-specific): Shipped on dry ice packs + cold packs to maintain ultra‑low temperature.
• Container handling
  • Keep tightly sealed under dry, inert conditions where possible. Allow vials to equilibrate to room temperature in a desiccator before opening to minimize condensation.
• Reconstitution (general guidance, not item-specific)
  • Prepare concentrated stocks in anhydrous DMSO. Example: 10–50 mM. Mix by gentle vortexing or brief sonication.
  • If aqueous formulations are required, add DMSO stock to buffer slowly with vigorous mixing to avoid precipitation; verify clarity and stability.
• Aliquoting
  • Divide into single-use aliquots to avoid repeated freeze–thaw. Record freeze–thaw count for each aliquot.
• Solution stability
  • Absent item-specific data, use freshly prepared working solutions and discard after use. For longer storage, keep frozen at -80°C in amber vials; confirm stability by analytical QC (e.g., LC‑MS) before critical experiments.
• Research use only: Not for human or veterinary use.
