LHA585 is a fluorescent probe targeting the lipid hydrogen abstraction process for the early detection of ferroptosis (Ferroptosis). Its detection mechanism relies on the reactivity of its own 4-phenyl-3-methylbut-2-enyl moiety with biologically relevant oxidative radicals, including peroxyl radicals (ROO·), alkoxyl radicals (RO·), hydroxyl radicals (HO·), and peroxynitrite anions (ONOO−); upon hydrogen abstraction from this structure, radical rearrangement and radical cleavage occur, releasing a xanthene radical which converts into a highly fluorescent rhodamine dye in biological environments, thereby achieving a fluorescence turn-on ratio of up to 360-fold. LHA585 is non-fluorescent in its native state, possesses excellent membrane permeability due to its non-polar property, and the rhodamine dye generated after oxidation diffuses into mitochondria. The excitation wavelength of LHA585 is 561 nm, and its emission wavelength ranges from 570 to 620 nm .

The high rates of morbidity and mortality caused by fungal infections are associated with the current limited antifungal arsenal and the high toxicity of the compounds. Additionally, identifying novel drug targets is challenging because there are many similarities between fungal and human cells. The most common antifungal targets include fungal RNA synthesis and cell wall and membrane components, though new antifungal targets are being investigated. Nonetheless, fungi have developed resistance mechanisms, such as overexpression of efflux pump proteins, overexpression and changes in drug targets and biofilm formation, emphasizing the importance of discovering new antifungal drugs and therapies. Due to the limited antifungal arsenal, researchers have sought to improve treatment via different approaches, such as the combination of antifungal drugs, development of new formulations for antifungal agents and modifications to the chemical structures of traditional antifungals, etc.

MCE offers a unique collection of 585 compounds with validated antifungal activities. MCE antifungal compound library is an effective tool for drug repurposing screening, combination screening and biological investigation.

Neurotransmitter (NT) receptors, also known as neuroreceptors, are a broadly diverse group of membrane proteins that bind neurotransmitters for neuronal signaling. There are two major types of neurotransmitter receptors: ionotropic and metabotropic. Ionotropic receptors are ligand-gated ion channels, meaning that the receptor protein includes both a neurotransmitter binding site and an ion channel. The binding of a neurotransmitter molecule (the ligand) to the binding site induces a conformational change in the receptor structure, which opens, or gates, the ion channel. The term “metabotropic receptors” is typically used to refer to transmembrane G-protein-coupled receptors. Metabotropic receptors trigger second messenger-mediated effects within cells after neurotransmitter binding.

In some neurological diseases, the neurotransmitter receptor itself appears to be the target of the disease process. Many neuroactive drugs act by modifying neurotransmitter receptors. A better understanding of neurotransmitter receptor changes in disease may lead to improvements in therapy.

MCE designs a unique collection of 2,593 compounds targeting a variety of neurotransmitter receptors. MCE Neurotransmitter Receptor Compound Library is a useful tool for neurological diseases drug discovery.

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 .

Spirocyclic compounds, with rigid 3D structures, high Fsp³ and strong conformational restriction, are highly privileged scaffolds in small-molecule drug screening. They overcome drawbacks of planar aromatic compounds such as poor solubility, high off-target risks and weak druggability. Their orthogonal bicyclic geometry fits well into protein pockets, improving target affinity, subtype selectivity, metabolic stability and membrane permeability, making them ideal for hit identification against kinases, GPCRs, PPIs and other targets.

Spirocyclic scaffolds have been widely applied in oncology, antivirals, hypertension and CNS diseases, leading to many approved drugs and clinical candidates. SAR studies show that spiro-atom chirality, ring size and heteroatom substitution dominate bioactivity and selectivity, with the scaffold mainly serving as a conformational anchor. Azaspirocycles, spirooxindoles and spirosteranes target GPCRs, kinases, MDM2-p53 and PPIs. Approved drugs including irbesartan, spironolactone and rolapitant confirm their druggability, while revumenib and SAR405838 show promise against undruggable targets.

The MCE Spirocyclic Druglike Library contains over 1,000 diverse, stereospecific molecules selected by Lipinski’s rules. It covers privileged cores such as azaspirocycles, oxaspirocycles and spirooxindoles. These molecules bear rich chiral centers and distinct 3D orientations, reducing non-specific binding and enhancing screening efficiency. Featuring novel scaffolds, the library offers a highly innovative starting point for drug discovery.
