HY-100017

BAY-876 50+ Cited Publications	GLUT Disulfidptosis	Cancer
BAY-876, a chemical probe, is an orally active and selective glucose transporter 1 (GLUT1) inhibitor with an IC₅₀ of 2 nM. BAY-876 is >130-fold more selective for GLUT1 than GLUT2, GLUT3, and GLUT4. BAY-876 is also a potent blocker of glycolytic metabolism and ovarian cancer growth. In addition, BAY-876 can induce the formation of disulfide bonds in actin cytoskeletal proteins, leading to the occurrence of cellular disulfidptosis .

HY-P2031

Phallacidin	Arp2/3 Complex	Others
Phallacidin is a natural bicyclic heptapeptide derived from the poisonous mushroom Amanita phalloides. Phallacidin binds to filamentous actin specifically with high affinity, with a K_d of 20 nM. After binding to F-actin, Phallacidin strongly inhibits its depolymerization, stabilizes microfilament structures, and prevents their disruption by drugs such as cytochalasins. When conjugated with a fluorophore, Phallacidin serves as a specific fluorescent probe for F-actin, which is used to clearly visualize the distribution of actin in the cytoskeleton (e.g., stress fibers, cortical peripheral bands) under fluorescence microscopy .

HY-174229

SM311	LIM Kinase (LIMK)	Neurological Disease Cancer
SM311 (Compound 10), a chemical probe, is a potent selective irreversible LIMK1 inhibitor (EC₅₀=0.045 μM, >30-fold selective over LIMK2). SM311 blocks cofilin phosphorylation and actin cytoskeleton regulation. SM311 is promising for research of neurodegenerative diseases like Fragile X syndrome (FXS) and Alzheimer’s disease, as well as tumor invasion .

HY-17672

Jasplakinolide probe-1	Drug Derivative	Cancer
Jasplakinolide probe-1 (Compound 12), a Jasplakinolide (HY-P0027) derivative, is a Jasplakinolide probe. Jasplakinolide probe-1 shows anti-proliferative activity and can inhibit the dynamics of actin, cause the collapse of cell lamellipodia, interfering with the dynamic balance of actin. Jasplakinolide probe-1 can be used for imaging of actin structure in cells conjugated with a fluorescent dye .

HY-D3306

Tubulin-RedTracker	Fluorescent Dye	Others
Tubulin-RedTracker is a paclitaxel-derived fluorescent microtubule-binding probe. Tubulin-RedTracker induces F-actin cytoskeleton defects at relatively high concentrations. (Ex/Em=652/669) .

HY-100017R

BAY-876 (Standard)	Reference Standards GLUT Disulfidptosis	Cancer
BAY-876 (Standard) is the analytical standard of BAY-876 (HY-100017). This product is intended for research and analytical applications. BAY-876, a chemical probe, is an orally active and selective glucose transporter 1 (GLUT1) inhibitor with an IC50 of 2 nM. BAY-876 is >130-fold more selective for GLUT1 than GLUT2, GLUT3, and GLUT4. BAY-876 is also a potent blocker of glycolytic metabolism and ovarian cancer growth. In addition, BAY-876 can induce the formation of disulfide bonds in actin cytoskeletal proteins, leading to the occurrence of cellular disulfidptosis .

HY-D3153

PbQ	Apoptosis Caspase Microtubule/Tubulin	Inflammation/Immunology
PbQ is a tubulin inhibitor (with an IC₅₀ of 5 μM against goat tubulin) and a fluorescent probe for cuprous ions Cu (I). PbQ can penetrate the membrane of peripheral blood mononuclear cells, form a stable 1:1 complex with Cu ⁺ ions, and exhibits low toxicity and good biocompatibility toward macrophage cell lines. In addition, PbQ promotes tubulin degradation and disrupts the microtubule network in lung epithelial cells without affecting actin. PbQ also possesses genotoxicity by forming DNA base adducts, and it can activate caspase-3 and apoptosis-related genes, induce loss of mitochondrial membrane potential, and trigger cell apoptosis. PbQ can be used in studies related to chronic obstructive pulmonary disease .
