T-0632 is a CCK A receptor antagonist that exhibits significant pharmacological properties in in vitro studies. T-0632 competitively inhibits the binding of [125I]CCK-8 to rat pancreatic CCK A receptors with a K_i value of 0.24 nM, which is significantly lower than the K_i value for guinea pig CCK B receptors. T-0632 has higher selectivity in inhibiting CCK-8-stimulated pancreatic enzyme release, with an IC_50 value of 5.0 nM, which is more advantageous than L-364,718 and loxiglumide. In rabbit gallbladder smooth muscle, the antagonistic effects of T-0632 and loxiglumide are reversible, while L-364,718 shows a persistent inhibitory effect. These results indicate that T-0632 is a highly potent, reversible and more selective CCK A receptor antagonist.

Sweroside (Standard) is the analytical standard of Sweroside (HY-N0806). This product is intended for research and analytical applications. Sweroside is an iridoid glycoside that targets multiple targets, including the Keap1/Nrf2 axis, NLRP3 inflammasome, SIRT1, NF-κB, AMPK/mTOR pathway, and caspase family. Sweroside promotes Nrf2 nuclear translocation by competitively binding to Keap1. Sweroside also inhibits oxidative stress and NLRP3-mediated pyroptosis by activating Nrf2, inhibits NF-κB inflammatory pathway by activating SIRT1, and promotes autophagy and induces caspase-dependent apoptosis via the AMPK/mTOR pathway. Sweroside has antioxidant, anti-inflammatory, anti-apoptotic, and lipid metabolism regulating activities, and can be used in the research of myocardial ischemia-reperfusion injury, leukemia, acute lung injury, non-alcoholic fatty liver disease, and other fields .

Research Areas:  

Cancer

UE01 is an orally active, selective small-molecule modulator targeting both ULK1/ERK1/2. UE01 activates hULK1 with an EC50 of 695.30 nM and a KD of 114.3 nM for ULK1; it inhibits hERK1 with an IC50 of 179.90 nM and a KD of 114 nM for ERK1; it shows weak binding to ERK2 with a KD of 2.8 mM. UE01 induces the conformational transition of ULK1 from an inactive to an active state, enhances the phosphorylation of ULK1 Ser317 and mAtg13 Ser355, and reduces the phosphorylation of ULK1 Ser757. UE01 competitively occupies the ATP-binding pocket of ERK1, inhibits ERK1 kinase activity, and reduces the activity of the ERK1/2 signaling pathway. UE01 induces complete autophagy flux and apoptosis, upregulates Atg5, Atg7, LC3-II/LC3-I, Bax, cytochrome C (Cyt c), Cleaved-Caspase 3, Cleaved-PARP1 and E-cadherin, downregulates p62, Bcl-2, MMP-2 and MMP-9, reduces the phosphorylation of Exo70 Ser250, and promotes the proteasome-dependent degradation of Cav-1, thereby inhibiting EMT-related phenotypes and extracellular matrix degradation. UE01 can be used in studies related to triple-negative breast cancer .

RSS0680 is a small noncoding RNA (sRNA) targeting the mRNA ribosome binding site (RBS) and a PROTAC. RSS0680 competitively binds to RBS through the conserved CCUCCUCCC anti-Shine-Dalgarno (aSD) sequence and inhibits the translation initiation of target genes. RSS0680 can interact with the DUF1127 protein CcaF1, regulate its own stability and participate in bacterial oxidative stress defense, enhancing the host's resistance to heat shock and oxidative damage by affecting pathways such as C1 metabolism and pyruvate dehydrogenase complex. RSS0680 degrades AAK1, CDK1, CDK16, CDK2, CDK4, CDK6, EIF2AK4, GAK, LATSl, LIMK2, MAPK6, MAPKAPK5, MARK2, MARK4, MKNK2, NEK9, RPS6KB1, SIK2, SNRK, STK17A, STK17B, STK35, and WEEl. RSS0680 can be used to study diseases or disorders mediated by aberrant kinase activity and regulatory mechanisms of noncoding RNAs in α-proteobacteria[1][2].

L-699333 is a 5-lipoxygenase (5-LO) inhibitor belonging to the thieno[2,3,4-cd]indole class. This compound has a 2-ethoxybutyric acid side chain and is a potent inhibitor of the biosynthesis of 5-HPETE and LTB4 produced from human 5-LO, with ICm values of 22 nM, 7 nM, and 3.8 pM for human neutrophils and whole blood, respectively. L-699333 has shown anti-inflammatory and antiasthmatic effects in a variety of animal models, including rat pleurisy models, antigen-induced wheezing models, and awake macaque and sheep asthma models. Its inhibition of 5-LO is highly selective, with higher ICm values or stronger competitive inhibition in FLAP binding assays compared to inhibition of human 15-LO, porcine 12-LO, and ram epididymal cyclooxygenase. The racemic enantiomer 14g of L-699333 is the most potent enantiomer to date, with inhibitory effects similar to those of the known MK-0591, which has been shown in clinical trials to inhibit the biochemical effects of LTB4 biosynthesis in vitro and LTE4 excretion in urine.

Research Areas:  

Cancer

Lazertinib (YH25448; GNS-1480) mesylate hydrate is an orally active, blood-brain barrier permeable third-generation EGFR tyrosine kinase inhibitor, as well as an ABCB1/ABCG2 inhibitor and a TRPA1 activator. Lazertinib mesylate hydrate exhibits IC50 values of 0.4 mM and 0.2 mM against human ABCB1 and ABCG2, respectively. By inhibiting mutant EGFR signaling, EGFR phosphorylation and the downstream ERK/AKT pathway, as well as upregulating surface expression of EGFR/MET, Lazertinib mesylate hydrate induces cell cycle arrest, apoptosis, spontaneous calcium responses, hyperexcitability of dorsal root ganglion (DRG) neurons, and TRPA1-dependent pain-like behaviors. Lazertinib mesylate hydrate competitively binds to the substrate-binding sites of ABCB1/ABCG2, stimulates their ATPase activity without altering their expression or plasma membrane localization, thereby enhancing ADCC activity, acting as a chemosensitizer, and reversing ABCB1-mediated multidrug resistance. It exerts antitumor activity as a single agent or in combination with other drugs. Lazertinib mesylate hydrate is applicable to research related to non-small cell lung cancer, multidrug-resistant cancers, and paresthesia .

AZD5099 inhibits rat Mrp2 ATPase activity, competitively binds to the ATP-binding site of bacterial type II topoisomerases, blocks enzyme activity, reduces bacterial DNA and RNA synthesis, disrupts DNA replication and transcription processes, and induces mitochondrial toxicity. AZD5099 exhibits activity against Gram-positive bacteria, fastidious Gram-negative bacteria and drug-resistant strains, reduces bacterial loads in mouse infection models, and has a low spontaneous resistance frequency. AZD5099 can be used in studies related to infections caused by Gram-positive bacteria and fastidious Gram-negative bacteria, methicillin-resistant Staphylococcus aureus infections, Streptococcus pneumoniae pulmonary infections, as well as Staphylococcus aureus and Escherichia coli infections .
