Leupeptin Ac-LL hydrochloride is a broad-spectrum protease inhibitor . By inhibiting the activation of the PTEN/PI3K/Akt/NF-κB/ERK1/2/p38 signaling pathway, Leupeptin Ac-LL hydrochloride significantly reduces LPS-induced NO and ROS production, mitochondrial membrane potential hyperpolarization, phagocytic activity, pro-inflammatory cytokine release, and M1 polarization in mouse peritoneal macrophages, and reverses autophagic flux impairment. It also decreases Concanavalin A (HY-P2149)-induced proliferation index of mouse splenic lymphocytes and the Th1/IL-10 and Th2/IL-10 cytokine ratios, thereby modulating innate and adaptive immune responses. Leupeptin Ac-LL hydrochloride inhibits blood coagulation and tumorigenesis in mouse skin. Leupeptin Ac-LL hydrochloride can be used in research on chronic inflammatory diseases and skin tumorigenesis .

AAP-SO2 is a Bactericide and Mycobacterium tuberculosis RNA polymerase (Mtb RNAP) inhibitor, with an IC50 of 0.025 μM against Mtb RNAP. AAP-SO2 allosterically slows the nucleotide addition rate during transcriptional elongation and enhances transcription termination efficiency. AAP-SO2 exhibits increased activity against β S450L-type Mtb, possesses activity against non-replicating Mtb, and shows whole-cell activity against Mtb and related mycobacterial species. AAP-SO2 reduces the overall emergence rate of Rifampicin (HY-B0272) tolerance in Mtb, alters the mutation spectrum, and decreases the proportion of β S450L-type Rifampicin-resistant mutants. AAP-SO2 acts synergistically with Rifampicin to kill non-replicating Mtb in a rabbit caseous necrosis model. AAP-SO2 can be used for the research of tuberculosis .

Thiacloprid-d4 is the deuterium labeled Thiacloprid. Thiacloprid is an orally active neurotoxic insecticide and also a nAChR agonist. Thiacloprid reduces the viability of healthy cells, depletes reduced glutathione, and increases MDA levels, thereby inducing cytotoxicity and oxidative stress damage. In practical applications, Thiacloprid has lower acute toxicity to honeybees than other compounds of the same class such as Imidacloprid (HY-B0838), but it still significantly impairs the learning and memory function, immune capacity and survival status of honeybees. Thiacloprid induces intestinal microbial dysbiosis and reduces survival rate in middle-aged honeybees, increases the risk of premature collapse in bumblebee colonies, and significantly decreases the final colony weight and reproductive output. Thiacloprid is used in broad-spectrum agricultural pest control, often alone or in combination with Deltamethrin (HY-B1971), and meets the pest management needs of various crops including potatoes, cabbages, various fruits and vegetables, and nuts .

2',7'-Difluorofluorescein (Oregon green 488) is a fluorescein derivative and a pH-sensitive fluorescent probe (pKa ~4.7). Upon excitation at 488 nm, 2',7'-Difluorofluorescein exhibits pH-sensitive fluorescence intensity through the formation of dianions, while its pH sensitivity decreases under excitation at 450 nm, allowing its use in ratiometric pH analysis. 2',7'-Difluorofluorescein can be used for the quantitative analysis of pH values in the range of 2-7 in submicron aerosol particles. 2',7'-Difluorofluorescein undergoes buffer-mediated and buffer-free excited-state proton transfer between different protonated forms, and its cationic form undergoes rapid excited-state deprotonation. 2',7'-Difluorofluorescein is resistant to photodegradation, maintains stable absorption and fluorescence properties within the physiological pH range, and serves as a fluorescent protein label, a component of Ca 2+ indicators, a fluorescent imaging agent, and an anisotropy probe .
