Canagliflozin (hemihydrate): Precision SGLT2 Inhibitor for Diabetes Research

Executive Summary: Canagliflozin (hemihydrate) is a high-purity small molecule SGLT2 inhibitor used in metabolic and diabetes research (product page). Its mechanism involves inhibiting renal glucose reabsorption via SGLT2, thereby lowering blood glucose levels. The compound demonstrates robust solubility in organic solvents but is insoluble in water. Recent peer-reviewed findings confirm that Canagliflozin does not inhibit mTOR pathways, establishing its mechanistic selectivity (Breen et al. 2025). This article provides a structured overview of its properties, evidence base, best practices, and boundaries.

Biological Rationale

Canagliflozin (hemihydrate), also known as JNJ 28431754 hemihydrate, is a research-grade SGLT2 inhibitor. SGLT2 is a sodium-glucose cotransporter prominently expressed in the renal proximal tubules. It mediates reabsorption of filtered glucose from the glomerular filtrate. Inhibition of SGLT2 leads to increased urinary glucose excretion, reducing plasma glucose concentrations. This mechanism is relevant for dissecting glucose homeostasis and pathologies such as type 2 diabetes mellitus (contrast: builds on strategic SGLT2 inhibition insights). High-purity SGLT2 inhibitors like Canagliflozin facilitate pathway-specific research, minimizing off-target effects common to less selective agents (extends: details pathway selectivity and rigor).

Mechanism of Action of Canagliflozin (hemihydrate)

Canagliflozin is a small molecule (C₂₄H₂₆FO_5.5S, MW 453.52) that selectively inhibits SGLT2 in the kidney. SGLT2 is responsible for approximately 90% of renal glucose reabsorption. By competitively binding to the transporter, Canagliflozin blocks glucose reuptake from the filtrate, resulting in glucosuria and lowered blood glucose. This effect is independent of insulin secretion or sensitivity (clarifies: emphasizes systems-biology perspective). Canagliflozin (hemihydrate) exhibits poor aqueous solubility but dissolves readily in ethanol (≥40.2 mg/mL) and DMSO (≥83.4 mg/mL). It is chemically stable at -20°C and should be handled under these conditions for optimal integrity (ApexBio product C6434).

Evidence & Benchmarks

• Canagliflozin (hemihydrate) demonstrates ≥98% purity as confirmed by HPLC and NMR in research-grade preparations (ApexBio C6434).
• It is insoluble in water, but soluble in DMSO (≥83.4 mg/mL) and ethanol (≥40.2 mg/mL) at 25°C (product page).
• Canagliflozin is a potent, selective inhibitor of SGLT2, with negligible activity against SGLT1 under research conditions (internal benchmark).
• Peer-reviewed screening confirms Canagliflozin does not inhibit the mTOR pathway in yeast-based models (Breen et al. 2025, DOI).
• Recommended storage is at -20°C; solutions are not stable for long-term storage and should be used promptly (product page).
• Experimental validation shows Canagliflozin (hemihydrate) is effective for dissecting renal glucose reabsorption and glucose homeostasis (internal: clarifies specificity versus mTOR).

Applications, Limits & Misconceptions

Canagliflozin (hemihydrate) is optimized for research in glucose metabolism, renal glucose transport, and diabetes mellitus. Its chemical and biological selectivity make it suitable for pathway dissection and pharmacodynamic modeling in metabolic disorder studies. The compound is not approved for diagnostic or clinical use; it is strictly intended for research applications. When used in yeast-based mTOR screening assays, Canagliflozin shows no evidence of TOR inhibition, distinguishing its mechanism from mTOR inhibitors (Breen et al. 2025).

Common Pitfalls or Misconceptions

• Not an mTOR inhibitor: Comprehensive screening shows no TOR inhibition (DOI).
• Not soluble in water: Attempting water-based dissolution fails; use DMSO or ethanol as solvents (source).
• Not intended for diagnostics: Research use only; not for in vivo or therapeutic application.
• Rapid solution degradation: Do not store solutions long-term; prepare fresh aliquots for each use.
• No effect on SGLT1 under normal assay conditions: SGLT2 selectivity is key for pathway-specific studies.

Workflow Integration & Parameters

For optimal results, Canagliflozin (hemihydrate) should be dissolved in DMSO or ethanol at room temperature (25°C). Aliquots should be stored at -20°C and protected from light. Solutions should be used promptly after preparation. Protocols typically employ concentrations ranging from 0.1 to 100 μM for in vitro models. For studies targeting glucose homeostasis pathways, Canagliflozin facilitates quantifiable glucosuria and measurable reductions in extracellular glucose. The C6434 kit is shipped on blue ice to maintain compound integrity during transit.

Conclusion & Outlook

Canagliflozin (hemihydrate) is a validated, high-purity SGLT2 inhibitor for research on glucose metabolism, diabetes, and renal physiology. Its selectivity and well-characterized properties make it a benchmark tool for metabolic disorder research. Recent mTOR screening studies reinforce its specificity, helping researchers avoid mechanistic confounds. Ongoing advances in workflow integration and comparative analysis position Canagliflozin (hemihydrate) as a cornerstone reagent in metabolic and diabetes research (ApexBio C6434).
