D-Histidine (Standard)	Microorganisms Source Classification	Reference Standards Mitochondrial Metabolism Bacterial
D-Histidine (Standard) is the analytical standard of D-Histidine (HY-W012572). This product is intended for research and analytical applications. D-Histidine is an anti-biofilm agent that targets bacterial quorum sensing systems (such as RhlI/RhlR pathway) and has antibacterial activity. D-Histidine works by non-covalently binding to bacterial regulatory factors or copper ion complexes, selectively inhibiting bacterial biofilm formation and motility. D-Histidine downregulates quorum sensing-related gene expression, reduces the synthesis of virulence factors (such as alginate and proteases), and interferes with bacterial membrane stability, inhibiting biofilm formation, promoting the disintegration of mature biofilms, and enhancing antibiotic sensitivity. D-Histidine is also an efficient catalyst for the salt-induced peptide formation (SIPF) reaction, which promotes the condensation of amino acids to form dipeptides (such as dialanine and dilysine) by forming a complex with copper ions (Cu ²⁺) .

Tubulosine	Structural Classification Alkaloids Other Alkaloids Rubiaceae Plants Pogonopus tubulosus (A.Rich. ex DC.) K.Schum. Source Classification	JAK Apoptosis Autophagy
Tubulosine is an alkaloid. Tubulosine can be isolated from Pogonopus tubulosus (DC.) Schumann. Tubulosine is an ATP-competitive, selective JAK3 inhibitor with an IC₅₀ value of 9.9 nM. Tubulosine also inhibits the kinase activities of other JAK family members, the extent of inhibition is less than that of JAK3, with IC₅₀ values of 69.5, 84.9 and 76.3 nM for JAK1, JAK2 and TYK2, respectively. Tubulosine selectively inhibits JAK3 signalling by binding to the ATP-binding site of the kinase of JAK3. Tubulosine induces apoptotic and necrotic/autophagic cell death. Tubulosine inhibits the process of peptide chain elongation by eukaryotic polysomes by, specifically preventing the elongation-factor-2-dependent step of translocation. Tubulosine exhibits anticancer activity in breast cancer cells .

Ercalcitriol-d3

Ercalcitriol-d₃ (1α,25-Dihydroxy Vitamin D2-d₃) is the deuterium labeled Ercalcitriol (HY-32350). Ercalcitriol (1α,25-Dihydroxy Vitamin D2) is a vitamin D receptor (VDR) agonist with high binding affinity. After binding to VDR, Ercalcitriol forms a complex with retinoid X receptor (RXR) to regulate target gene transcription. For example, Ercalcitriol induces human gingival/oral epithelial cells to produce human cat antimicrobial peptide (hCAP-18/LL-37), which has antimicrobial activity against periodontal pathogens such as Porphyromonas gingivalis. Ercalcitriol enhances the innate immune defense of the oral mucosa by promoting the expression of antimicrobial peptides, and is mainly used in the study of periodontal diseases and immune-related oral diseases .
