Overview

Information

TMP195 TMP195 (TFMO 2) is a selective, first-in-class, class IIa HDAC inhibitor with IC50 of 300 nM in cell-based class IIa HDAC assays.
In vitro

TMP195 has low potency in recombinant class I and IIb HDAC assays, enabling full inhibition of class IIa HDAC activity without inhibition of other HDACs. TMP195 blocks the accumulation of CCL2 protein in the supernatants of monocyte-derived macrophage differentiation cultures and significantly increases the amount of CCL1 protein secreted by the monocytes compared to vehicle (DMSO)-treated M-CSF plus GM-CSF cultures. TMP195 influences human monocyte responses to the colony-stimulating factors CSF-1 and CSF-2 in vitro.

In vivo

In vivo TMP195 treatment alters the tumour microenvironment and reduces tumour burden and pulmonary metastases by modulating macrophage phenotypes. TMP195 induces the recruitment and differentiation of highly phagocytic and stimulatory macrophages within tumours. TMP195 treatment significantly decreases proliferating tumour cells, most notably at the leading edge of the tumour. The anti-tumour macrophage phenotype induced by TMP195 treatment thus enhances the efficacy and durability of both standard chemotherapeutic regimens and checkpoint blockade immunotherapy in this mouse model of breast cancer.

Application Protocols

No item-specific tested applications are provided in the listing. The following general practices are commonly used for small-molecule research compounds.

General small-molecule handling

• Reconstitution (stock): Dissolve the solid in anhydrous DMSO to prepare a concentrated stock (e.g., 10–50 mM). If insoluble, consider warming gently to 30–37°C and brief sonication. Do not exceed temperatures that may degrade the compound.
• Aliquoting: Dispense into single-use or limited-use aliquots in low‑bind tubes or 96/384‑well source plates to minimize freeze–thaw.
• Working dilutions: Dilute into assay buffer or media immediately before use, targeting final DMSO within assay tolerance; vortex during addition to reduce precipitation.

Assay execution tips

• Include matched vehicle controls and, where possible, orthogonal controls (inactive analogs or alternate chemotypes) to validate phenotypes.
• For cell assays, confirm that plastic adsorption is not limiting exposure; pre-wet wells with media containing the final DMSO level or use low‑bind plates.
• Stability checks: For multi-hour incubations, verify compound stability in the assay matrix by LC‑MS or HPLC.

Documentation

• Record lot number, reconstitution solvent, concentration, and number of freeze–thaw cycles for reproducibility.

Biological Roles

Item-specific biological target information is not provided in this listing. Therefore, no claims about target class, potency, or selectivity are made here. Consult primary literature or the product’s CoA/Spec Sheet if target information is needed for your application.

General context for small-molecule research tools

• Small molecules are widely used to modulate protein function, interrogate signaling pathways, and validate phenotypic hypotheses across biochemistry, cell biology, and chemical biology.
• Mechanistic studies often pair chemical probes with orthogonal controls (structural analogs, inactive enantiomers, or genetic perturbations) to strengthen causality.
• Key considerations: off-target activity, metabolic stability in cell systems, and compound aggregation at higher concentrations; employ counterscreens and detergent controls as needed.

Experimental best practices

• Establish full concentration–response curves with appropriate vehicle controls.
• Verify compound integrity in the working plate by LC-MS where feasible, especially for multi-day assays or heated incubations.
• Track exposure metrics in cells (nominal vs intracellular concentration) when interpreting pharmacological effects.

This product is intended for research use only and is not for use in diagnostic or therapeutic procedures.

Buffer Applications

This item is a small-molecule library compound and is not itself a buffering agent. Therefore, conventional buffer system design (pH range, pKa, capacity) is not applicable.

Practical guidance for use with buffers (general)

• Dissolve the compound in DMSO (concentrated stock), then dilute into the desired buffer (e.g., PBS, HEPES, Tris) with vigorous mixing to avoid precipitation.
• Maintain consistent final DMSO across control and treated samples to avoid vehicle artifacts.
• If adsorption losses are suspected, low levels of non-ionic surfactant (e.g., 0.01% Tween-20) can improve recovery; validate that the surfactant does not affect your assay.

Green Alternatives

For screening-library tool compounds like this item, “green alternatives” pertain primarily to solvent and workflow choices rather than replacing the compound itself.

Greener practice suggestions (general)

• Prefer aqueous assay buffers with minimal DMSO carryover (≤0.1–0.5% v/v) when compatible with sensitivity and solubility.
• For analytics, consider ethanol or water-rich mobile phases where feasible; use acetonitrile judiciously due to supply and environmental factors.
• Use microscale assay formats (384/1536-well) to reduce solvent consumption and waste.
• Implement solvent recycling for LC where policy and instrumentation allow.

Illustrative comparison (general, not item-specific)

• DMSO vs 2‑propanol as co‑solvent: DMSO offers superior solvency and stability; 2‑propanol is more volatile and generally considered greener but may limit solubility and introduce assay volatility.
• ACN vs MeOH in LC: ACN yields sharper peaks and lower backpressure; MeOH is less hazardous in some contexts but can raise viscosity and change selectivity.

Waste minimization

• Consolidate DMSO/organic waste streams and segregate halogenated solvents. Adopt just‑in‑time reconstitution to minimize expired solutions.

Pharmaceutical Uses

No pharmaceutical excipient or GMP/compendial status is provided for this item, and it is sold strictly for research use only.

Context (general)

• Research-only small molecules may be used in discovery-stage studies, target validation, and pre-formulation exploration within research settings. They are not intended for human or veterinary use, clinical diagnostics, or as drug substances.
• If downstream translational studies are envisioned, separate sourcing under GMP with full regulatory documentation, impurity profiling, and stability studies would be required.

Formulation notes for research settings (general)

• Typical working approach involves DMSO stock solutions and subsequent dilution into assay-compatible media. Solid-state properties (polymorph, hydrate, salt form) and stability—if relevant—should be verified from the CoA/Spec Sheet.

Statement

• For research use only. Not for human or animal therapeutic or diagnostic use.

General considerations (literature/practice, not item-specific)

• Many screening-library small molecules are supplied as dry powders and reconstituted in anhydrous DMSO to create concentrated stocks (e.g., 10–50 mM) before dilution into assay buffers or media.
• If the compound is hydrophobic, aqueous solubility may be limited; co‑solvents (DMSO), surfactants (e.g., 0.01–0.05% Tween-20), or pH adjustment are common strategies to achieve working concentrations.
• Light and moisture sensitivity vary by chemotype; protect from light and humidity until item-specific details are confirmed.

Always defer to the item’s CoA/SDS for authoritative physicochemical data.

Quality and Grades

• Grade/Purity: Not specified for this item; refer to CoA/Spec Sheet.

How to interpret grades (general guidance)

• Research-grade small molecules are typically suitable for in vitro assays, screening, and mechanism studies. When “HPLC” or “≥X% purity” is specified on a CoA, it commonly refers to area% by HPLC at a defined wavelength/method. Low-UV-absorbing solvents and stabilized storage conditions are used to maintain purity.
• If a stabilizer is present, it will be declared on the label/CoA. Stabilizers can influence bioassay backgrounds and mass spec signals; if present, consider additional purification or matched vehicle controls.

Batch-specific documentation

• Certificate of Analysis (CoA) will list assay method(s) (e.g., HPLC/LC-MS), purity, residual solvents, and water content if determined, as well as lot-specific identification tests (NMR/HRMS/IR).
• If you require defined impurity profiles, elemental analysis, salt form, or counter-ion content, request the latest CoA/Spec Sheet prior to experimental use.

Practical recommendations

• Verify identity/purity on receipt for critical applications (e.g., LC-MS check, quick 1H NMR where feasible).
• Maintain frozen, moisture-protected storage to preserve integrity; minimize freeze–thaw with small aliquots.

Solvent Selection

Item-specific solubility data are not provided; select solvents empirically based on assay and detection needs.

General guidance for small-molecule tool compounds

• Primary stock solvent: Anhydrous DMSO is the most common for library compounds due to broad solvency, compatibility with screening workflows, and low volatility.
• Secondary solvents: DMF, methanol, ethanol, or acetonitrile may be used for analytical preparation (e.g., LC-MS) or as co‑solvents.
• Aqueous use: Prepare a concentrated DMSO stock (e.g., 10–50 mM), then dilute into buffer/media. Keep final DMSO typically ≤0.1–0.5% v/v for cell assays, or per your assay tolerance.
• Buffers: PBS, HEPES, or assay‑specific buffers often require ≤0.01% non-ionic surfactant to prevent adsorption losses for hydrophobic chemotypes.
• Avoid: High salt during initial dissolution; instead, dissolve in organic solvent first, then titrate into aqueous phase with vigorous mixing to avoid precipitation.

Analytical considerations

• For LC-MS, acetonitrile/water with 0.1% formic acid (positive mode) or 5–10 mM ammonium acetate (negative mode) are common. Validate ionization behavior and monitor for adduct formation.

Comparison (general)

• DMSO: highest solvency, but can interfere biologically at >1%.
• MeOH/EtOH: miscible with water, volatile; may extract plastics.
• ACN: excellent for analytics; limited biological tolerance without dilution.

Storage and Reconstitution

Item-specific guidance provided

• Storage conditions: Store at -80°C (per product data). Maintain in a tightly closed container, protected from moisture and, if indicated on the label/CoA, from light.
• Shipping: Shipped on dry ice packs + cold packs (per product data) to preserve integrity during transit.

General best practices

• Long-term storage: Keep as a dry solid at -80°C. If solution stocks are required, prepare small, single-use aliquots in anhydrous DMSO and store at -80°C in sealed, inert-atmosphere vials when possible.
• Freeze–thaw: Avoid repeated freeze–thaw cycles. Thaw aliquots on ice or at room temperature just before use; promptly return unused sealed aliquots to -80°C.
• Moisture/light: Many small molecules are sensitive to moisture and/or light. Use desiccant, purge headspace with inert gas (N2/Ar) after opening, and store in amber containers if photosensitivity is suspected.
• Stability: Item-specific stability in solid and solution states is Not specified for this item; refer to CoA/Spec Sheet. As a conservative practice, limit DMSO stock storage to weeks at -80°C and remake as needed based on analytical confirmation.

Reconstitution notes

• Solvent choice and target stock concentration: Not specified for this item; typical practice is DMSO at 10–50 mM, adjusted to your assay needs.
