Biological Roles

General literature context (not item-specific claims):

• Verubulin is described in the literature as a microtubule-destabilizing small molecule that binds the colchicine site of tubulin. Such compounds reduce tubulin polymerization, perturbing microtubule dynamics central to mitosis, intracellular transport, and cell morphology.
• Consequences of microtubule disruption include mitotic arrest, activation of spindle-assembly checkpoint pathways, and induction of apoptotic signaling in proliferative cell systems (literature). These effects underpin widespread use as tool compounds in cell biology.
• Biochemical implications: Binding at the tubulin colchicine site is typically characterized by inhibition of tubulin assembly in purified protein assays and by decreased microtubule mass in fixed-cell immunofluorescence.

Important usage note: This product is supplied strictly for research use. Do not use for diagnostic or therapeutic purposes. Verify concentration-response relationships and vehicle tolerability in your specific biological system before experimental conclusions.

Buffer Applications

This listing is a discrete hydrophobic small molecule, not a buffer component. It is not typically used to prepare pH-buffered solutions.

Practical note: When introducing small-molecule stocks into buffered media for assays, pre-dissolve in an appropriate organic solvent (commonly DMSO), then dilute into the buffer while mixing to avoid precipitation. Maintain final solvent at levels compatible with the biological system.

Green Alternatives

Green chemistry considerations are not typically applied to a discrete research ligand. However, greener choices can be made in how you handle and deliver the compound:

• Prefer greener solvents for cleaning and sample prep where feasible (e.g., ethanol or isopropanol for glassware rinse) while maintaining DMSO for primary dissolution if required by solubility.
• Minimize DMF/NMP use; if needed, confine them to small-volume concentrates that are subsequently diluted into DMSO/buffer.
• Use miniaturized assay formats (96–384–1536-well) to reduce solvent consumption and waste.

Tradeoffs (general):

• Ethanol is greener but may not dissolve lipophilic ligands adequately; DMSO is more effective but less desirable environmentally and biologically at high percentages. Balance solubility needs with final vehicle tolerances.

Waste handling: Collect DMSO/DMF/NMP solutions and assay residues as hazardous organic waste per institutional SOPs.

Pharmaceutical Uses

No clinical or therapeutic uses are claimed or supported for this catalog item. For research use only.

Relevant R&D contexts (general, non-item-specific):

• Reference standard/control: Employed as a tool compound in discovery biology to benchmark tubulin-directed mechanisms in cell lines.
• Method development: Can be used to challenge analytical methods (stability-indicating HPLC/LC–MS) for hydrophobic, aromatic drug-like entities.
• Formulation research: Preliminary solubilization studies (co-solvents, cyclodextrins, lipid vehicles) to inform delivery strategies for similar chemotypes. Any such work should be exploratory and confined to nonclinical laboratories.

Physical Properties

Item-specific physical constants were not provided in the Product Data. Do not treat any value below as a specification for this catalog item.

Item data:

• Appearance: Not specified for this item; refer to CoA/Spec Sheet.
• Molecular Weight: Not specified for this item; refer to CoA/Spec Sheet.

General/literature guidance for handling similar small molecules (non-binding):

• Solubility (literature/common practice): Many hydrophobic screening ligands are sparingly soluble in water and show good solubility in polar aprotic solvents such as DMSO and DMF; ethanol can be an auxiliary solvent for co-solubilization.
• Stock preparation (practice): 10–50 mM DMSO stocks are commonly prepared for small-molecule screening; vortex, brief sonication, or gentle warming (≤40 °C) can aid dissolution. Filter through 0.2 µm PTFE if particulate remains.
• LogP/ionization: Verubulin-class scaffolds are typically lipophilic and weakly basic/neutral (literature), implying high membrane permeability and low aqueous solubility.

Always consult the item’s CoA/Spec Sheet for authoritative physico-chemical values before designing experiments.

Solvent Selection

This product is a small, hydrophobic research ligand. No item-specific solubility data are provided; suggestions below are general/literature practice, not specifications.

• Primary solvent for stocks: DMSO is typically preferred due to high solubilizing power and compatibility with biological assays. Start with 10–20 mM.
• Secondary solvents: DMF or NMP can dissolve challenging solids; for assay use, back-dilute concentrated DMF/NMP stocks into DMSO, then into aqueous buffer with surfactant if needed.
• Co-solvent strategies: For aqueous delivery, pre-dilute DMSO stock into buffer containing 0.01–0.1% non-ionic surfactant (e.g., Tween-20) or 0.5–1% PEG-400 to mitigate precipitation (literature practice). Keep final DMSO ≤0.1–1% v/v as assay permits.
• Polarity/miscibility (general): Verubulin-like scaffolds are non-ionic and lipophilic; expect limited water solubility, good solubility in polar aprotics (DMSO/DMF) and moderate solubility in alcohols (MeOH/EtOH).

Comparison (general):

• DMSO vs ethanol: DMSO typically affords higher solubility and better freeze–thaw stability; ethanol offers lower cytotoxic vehicle but often poorer solubility.
• Aqueous buffers: Not recommended for primary dissolution; use only for final dilutions from an organic stock.

Confirm your solvent choice by small-scale solubility testing before committing to large assays.
