2-Methylbutanal
Based on 1 Customer Validation
2-Methylbutanal (2-Methylbutyraldehyde) is a short-chain aliphatic aldehyde and a characteristic volatile biomarker that can be used to detect the urinary tract pathogen Proteus. 2-Methylbutanal is an orally active CaSR activator and ENO1 inhibitor (Kd = 4.92 μM). 2-Methylbutanal activates oral CaSR to enhance the umami and salty taste of food. 2-Methylbutanal downregulates YAP1 by inhibiting the RNA-binding function of ENO1, thereby upregulating HPGD and reducing PGE2 production, ultimately relieving immunosuppression to promote the infiltration and activation of intratumoral CD8+ T cells. 2-Methylbutanal can be used in research on bacterial infections, colorectal cancer, and food flavor modulation.

In Vitro
2-Methylbutanal (2-Methylbutyraldehyde) (300 μM; 48 h) binds to ENO1 protein in HCT116 cells and attenuates the binding of ENO1 to YAP1 mRNA, thereby reducing YAP1 protein expression[5].
2-Methylbutanal (30-300 μM) significantly downregulates intracellular and conditioned medium PGE2 levels and upregulates HPGD expression in HCT116 cells[5].
2-Methylbutanal (up to 300 μM; 24-48 h) increases immunogenic cell death signals (such as promoting HMGB1 release and calreticulin exposure) in HCT116 and SW480 without significantly directly affecting tumor cell viability or proliferation[5].
2-Methylbutanal (30-300 μM; 24-48 h) exerts an antitumor effect in PBMC co-culture systems with HCT116 or SW480 by reducing target tumor cell viability in an immune cell-dependent and concentration-dependent manner[5].
2-Methylbutanal directly binds recombinant human ENO1 with a Kd of 4.92 μM[5].
2-Methylbutanal, as one of the C3-C6 aliphatic aldehydes, activates human CaSR in a structure-dependent manner in PEAKrapid cells expressing CaSR[1].

In Vitro:
DMSO : 100 mg/mL (1161.04 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (stored under nitrogen). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

In Vivo:
Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 5 mg/mL (58.05 mM); Clear solution
This protocol yields a clear solution of ≥ 5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (50.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.

Research Protocol for Infectious Diseases
Infectious-disease experiments test how pathogens interact with host barriers, innate immune receptors, inflammatory signaling, pathogen replication, and tissue injury; pattern-recognition receptors such as TLRs, RIG-I-like receptors, NOD-like receptors, and inflammasomes detect microbial molecules and activate NF-κB, interferon, and cytokine responses. The central hypothesis is that infection severity reflects the balance between pathogen burden and host response: protective inflammation restricts pathogen growth, whereas excessive or mislocalized inflammation contributes to tissue damage and disease phenotype. Unresolved questions include which host pathways are protective versus pathogenic, why some infection models fail to translate to human disease, and which combined readouts best predict clinically relevant infection outcomes.
