CAS No.: 6217-54-5
Synonyms: DHA (Standard); Cervonic acid (Standard)
Docosahexaenoic acid (Standard) is the analytical standard of Docosahexaenoic acid. This product is intended for research and analytical applications. Docosahexaenoic Acid (DHA) is an omega-3 fatty acid abundantly present brain and retina. It can be obtained directly from fish oil and maternal milk. In Vitro: Docosahexaenoic acid (DHA) is essential for the growth and functional development of the brain in infants. DHA is also required for maintenance of normal brain function in adults. The inclusion of plentiful DHA in the diet improves learning ability and memory . DHA is an essential requirement in every step of brain development like neural cell proliferation, migration, differentiation, synaptogenesis. The multiple double bonds and unique structure allow DHA to impart special membrane characteristics for effective cell signaling. Many development disorders like dyslexia, autism spectrum disorder, attention deficit hyperactivity disorder, schizophrenia etc. are causally related to decreased level of DHA . DHA is a potent RXR ligand inducing robust RXR activation already at low micro molar concentrations. The EC50 for RXRα activation by DHA is about 5-10 μM fatty acid . In Vivo: Docosahexaenoic acid administration over 10 weeks significantly reduces the number of reference memory errors, without affecting the number of working memory errors, and significantly increases the docosahexaenoic acid content and the docosahexaenoic acid/arachidonic acid ratio in both the hippocampus and the cerebral cortex . DHA treatment exerts neuroprotective actions on an experimental mouse model of PD. There is a decrease tendency in brain lipid oxidation of MPTP mice but it does not significantly .

Cancer

Ibetazol is a Importin β1 (KPNB1) inhibitor and nucleocytoplasmic transport disruptor. Ibetazol binds covalently to Cys585 of Importin β1, blocks both Importin β1-mediated direct transport and Importin α-dependent nuclear import processes, without affecting transport mediated by other nucleocytoplasmic transport proteins. Ibetazol induces cytoplasmic accumulation of Importin α1, and inhibits nuclear import of substrates carrying nuclear localization signals (NLS), including the NLS-cMyc reporter gene, RelA/p65 and SREBP1. Ibetazol triggers spindle malformation and chromosome misalignment by disrupting the mitotic function of Importin β1. Ibetazol inhibits the proliferation of cells expressing wild-type Importin β1. Ibetazol has a high activity-cytotoxicity window, lacks intrinsic fluorescence, and acts rapidly on nucleocytoplasmic transport processes. Ibetazol serves as a tool compound for investigating nuclear import processes specifically mediated by Importin β1 .

Fluorescent Dye

Research Areas:  

Others

Photoswitchable PM8 is a fluorescent probe used for super-resolution imaging of the plasma membrane. Photoswitchable PM8 functions through a light-induced Z/E isomerization mechanism: in the hydrophobic cell membrane environment, the Z isomer forms a planar intramolecular charge transfer state stabilized by an intramolecular hydrogen bond, which restricts conformational freedom, reduces nonradiative decay, and produces bright fluorescence; in contrast, the E isomer lacks this hydrogen bond, has increased conformational freedom, and exhibits a fluorescence-quenched state. The fluorescence of Photoswitchable PM8 can be switched "on/off" by visible light: activation with 405 nm light forms the fluorescent Z isomer, and switching with 561 nm light converts it to the nonfluorescent E isomer. In the membrane environment, Photoswitchable PM8 enables single-molecule localization for super-resolution imaging. Due to solvent-induced quenching and aggregation, Photoswitchable PM8 has negligible fluorescence in aqueous solution, but upon binding to the hydrophobic membrane environment it produces bright fluorescence, enabling high signal-to-noise ratio imaging without washing .

Infection

IP6C is a specific inhibitor and phage sensitizer targeting type II Thoeris systems. IP6C competitively binds to histidine in the catalytic pocket of ThsB, blocks the production of the His-ADPR alarm signal and inhibits ThsA activation, thereby relieving bacterial stasis of phage replication. IP6C selectively resensitizes drug-resistant bacteria carrying type II Thoeris systems (such as Pseudomonas aeruginosa) to phage lysis, without affecting other bacteria, and shows no toxicity to mice and human cell lines. IP6C significantly improves the survival rate of infected mice, and can be used to overcome bacterial phage defense mechanisms and study Pseudomonas aeruginosa infections .
Thoeris system: (named after the Egyptian goddess of fertility and protection), is a widespread anti-phage immune defense system in bacteria and archaea. Thoeris system belongs to the "Abortion Infection (Abi)" mechanism of bacteria: when an individual bacterium detects phage invasion, it initiates a suicide program and dies, thereby blocking phage replication and spread, and protecting the surrounding bacterial population from infection.

Synonyms: SHB 331 (Standard); WL 70 (Standard)
Gestodene (Standard) (SHB 331 (Standard); WL 70 (Standard)) is the analytical standard of Gestodene (HY-B0110). This product is intended for research and analytical applications. Gestodene is an orally active synthetic progestogen compound of the 19-nortestosterone class. Gestodene binds with high affinity to the progesterone receptor, inhibits 5α-reductase, binds to androgen and aldosterone receptors, and inactivates CYP3A. Gestodene acts as a positive allosteric modulator of PAR1, enhances PAR1-mediated signaling pathways, and is capable of increasing the activation potency of PAR1-AP toward PAR1, thereby promoting ERK1/2 phosphorylation, receptor internalization, cell morphological changes, and human platelet aggregation. Gestodene and its A-ring reduced metabolites promote the proliferation, differentiation, and mineralization of neonatal rat osteoblasts. Gestodene itself has no binding capacity for estrogen receptors, and this osteogenic activity depends on intracellular metabolism to generate A-ring reduced products with estrogen-like agonistic activity. Gestodene is useful for research on diseases related to progesterone secretion and diseases related to thrombosis .
