2-Aminoethyl-mono-amide-DOTA-tris(tBu ester) (Standard) is the analytical standard of 2-Aminoethyl-mono-amide-DOTA-tris(tBu ester) (HY-100138). This product is intended for research and analytical applications. 2-Aminoethyl-mono-amide-DOTA-tris(tBu ester) is a metal chelator precursor containing a DOTA macrocyclic structure. DOTA can form highly stable complexes with metal ions (such as 68Ga, 177Lu) through four nitrogen atoms and four carboxylic acid groups to mediate targeted delivery of radionuclides. The tert-butyl ester group (tBu ester) of 2-Aminoethyl-mono-amide-DOTA-tris(tBu ester) also protects the carboxylic acid group during synthesis, and forms a free carboxyl group after deprotection reaction for coupling with targeting molecules (such as antibodies, peptides). 2-Aminoethyl-mono-amide-DOTA-tris(tBu ester) may be combined with tumor pre-targeting systems through bioorthogonal reactions (such as reverse electron demand Diels-Alder reaction) to study radioactive imaging or therapy of tumor tissues, and is mainly used in tumor pre-targeting research in the field of nuclear medicine .

L18I is a Bruton's tyrosine kinase (BTK) PROTAC degrader that targets wild-type and BTK C481, and recruits the cereblon E3 ligase to mediate proteasomal degradation. L18I regulates the BCR, TLR, FcγR and NLRP3 inflammasome signaling pathways, inhibits the phosphorylation of PLCγ-2, ERK1/2 and p38, and reduces the levels of B cell activation markers CD25, CD69 and CD86. L18I downregulates the NF-κB, TNF and TLR signaling pathways, reduces the production of pro-inflammatory cytokines, and decreases immune cell infiltration and immune complex deposition. L18I inhibits the proliferation of BTK-expressing lymphoma cells, induces tumor regression in xenograft models, and exhibits synergistic activity when combined with inhibitors of SYK, PI3K or Lyn. L18I can be used in research related to lupus, diffuse alveolar hemorrhage and B-cell lymphoma .

Calcitroic acid-13C is the 13C-labeled Calcitroic acid (HY-N10508). Calcitroic acid is a water-soluble terminal vitamin D metabolite and also a ligand for vitamin D receptor (VDR). Calcitroic acid binds to the ligand-binding domain of VDR, forms a retinoic X receptor complex, recruits the coactivator peptide MED1, mediates partial VDR-dependent transcription, inhibits Calcitriol (HY-10002)-induced VDR activation, and reduces the transcription level of CYP24A1 in the presence of 1α,25-dihydroxyvitamin D3. Calcitroic acid exerts selective activating effects on VDR, upregulates the expression of CYP24A1 and CYP3A4, decreases the transcription levels of iNOS and IL-1β, reduces the secretion of nitric oxide and IL-1β, and possesses metabolic stability due to its resistance to phase I oxidation and hepatic glucuronidation. Calcitroic acid can be used in research related to colon cancer, inflammatory bowel disease and rickets .

TDI-015051 is a highly selective, orally active antiviral agent that targets the coronavirus NSP14 guanine-N7 methyltransferase. TDI-015051 binds to substrates in a non-competitive manner and forms a stable ternary complex, precisely blocking the capping and methylation processes of viral mRNA. TDI-015051 potently inhibits a variety of coronaviruses (including SARS-CoV-2 and MERS). By impairing viral replication and translation and inducing a moderate type I interferon-mediated immune response, it significantly reduces pulmonary viral load and exhibits a synergistic effect with Nirmatrelvir (HY-138687). In addition, TDI-015051 does not inhibit non-coronavirus methyltransferases, and the drug-resistant mutations it induces impair viral fitness, demonstrating excellent antiviral properties and safety. TDI-015051 can be used for research on COVID-19 and the replication mechanism of coronaviruses .The IC50 values of TDI-015051 against SARS-CoV-2, α-hCoV-NL63, α-hCoV-229E, β-hCoV-MERS are 0.15 nM, 1.7 nM, 2.6 nM and 3.6 nM, respectively, and the Ka value against SARS-CoV-2 is 0.061 nM .
