Decyl gallate is an antifungal (fungal) agent. Decyl gallate downregulates the expression of the pro-apoptotic (apoptosis) protein Bak, upregulates the expression of the anti-apoptotic protein Bcl-2, and inhibits DNA damage. Decyl gallate disrupts ALG12-mediated N-glycosylation, overactivates the UPR pathway, and simultaneously reduces fungal cell wall enzyme activity, chitin levels, mitochondrial activity, budding ability, cell viability, and host cell adhesion capacity. Decyl gallate reduces inflammatory responses induced by fungal infection and disrupts fungal membrane structure. Decyl gallate can be used in studies related to paracoccidioidomycosis and invasive fungal infections .

GALA-Cys is a chemically modified GALA peptide (HY-P5423) that retains GALA functions while acquiring strong covalent conjugation capability. GALA-Cys undergoes pH-driven reversible secondary structure transition, rearranges into an amphipathic α-helix, self-oligomerizes, penetrates lipid membranes to form pores, and disrupts lipid bilayers, thereby enabling endosomal escape and cytosolic cargo delivery. GALA-Cys can be conjugated with lipid DPTE for integration into liposomes, self-assembles into a tilted monolayer on gold surfaces, and serves as a pH-responsive coating for particle surface functionalization. GALA-Cys is applicable to studies related to targeted cargo delivery .

Infection Cancer

HA2 peptide is a potent pH-responsive fusion peptide derived from hemagglutinin (HA), corresponding to the N-terminal fusion peptide domain consisting of 23 amino acid residues of HIV-1 gp41 envelope glycoprotein. HA2 peptide adopts a random coil structure under physiological pH conditions; in acidic endosomes, protonation of carboxyl groups reduces negative charge, inducing a transition to an α-helical conformation that can fuse with and destabilize the endosomal membrane. After binding to membranes, the N-terminal and middle regions of HA2 peptide mainly adopt a β-strand conformation, while the C-terminal region remains unstructured. HA2 peptide induces lipid mixing and promotes aqueous content leakage from large unilamellar vesicles whose lipid composition matches that of HIV-1 viruses and target T cells. HA2 peptide is anionic and can bind to cationic peptides to achieve siRNA condensation. HA2 peptide can be used in studies related to cancer and human immunodeficiency virus (HIV) infection .

Prodan is an environment-sensitive fluorescent probe used to investigate the polarity, fluidity, and structure of lipid membranes. Prodan exhibits environment-dependent excitation/emission wavelengths, with its wavelength range covering Ex = 360-410 nm and Em = 430-530 nm when in solvents, bound to DNA, located in lipid bilayers, or associated with proteins. Prodan can interact with the major groove of DNA, regions of lipid bilayers, and hydrophobic pockets of proteins. During phase transitions, Prodan localizes to different regions of the bilayer: the emission minimum is 430-440 nm in the gel phase, while it shifts to 480-500 nm in the liquid-crystalline phase or interdigitated gel phase. When bound to rigid hydrophobic sites of proteins, the emission peak of Prodan undergoes a blue shift and its fluorescence intensity increases .

Most of molecules enter or leave cells mainly via membrane transport proteins, which play important roles in several cellular functions, including cell metabolism, ion homeostasis, signal transduction, the recognition process in the immune system, energy transduction, etc. There are three major types of transport proteins, ATP-powered pumps, channel proteins and transporters. Transport proteins such as channels and transporters play important roles in the maintenance of intracellular homeostasis, and mutations in these transport protein genes have been identified in the pathogenesis of a number of hereditary diseases. In the central nervous system, ion channels have been linked to, but not limited to, many diseases such asataxias, paralyses, epilepsies, and deafness. This indicates the roles of ion channels in the initiation and coordination of movement, sensory perception, and encoding and processing of information. Ion channels are a major class of drug targets in drug development.

MCE designs a unique collection of 2,278 smal-molecule modulators that can be used for the research of Ion Channel and Membrane Transporter or high throughput screening (HTS) related drug discovery.

Antibiotics are types of antimicrobial products used for the treatment and prevention of bacterial infections. Antibiotics can kill or inhibit bacterial growth. Although the target of an antibiotic is bacteria, some antibiotics also attack fungi and protozoans. However, antibiotics rarely have an effect on viruses. The major mechanism underlying antibiotics is the inhibition or regulation of enzymes involved in cell wall biosynthesis, nucleic acid metabolism and repair, protein synthesis, or disruption of membrane structure. Many of these cellular functions targeted by antibiotics are most active in multiplying cells. Since there is often overlap in these functions between prokaryotic bacterial cells and eukaryotic mammalian cells, it is not surprising that some antibiotics have also been found to be useful as anticancer agents.

MCE supplies a unique collection of 748 antibiotics, including penicillins, cephalosporins, tetracyclines, macrolides, etc. MCE Antibiotics Library is a useful tool for anti-bacterial or anti-cancer drugs discovery.

DCA is a Fluorescent probe for visualization of phase behavior in ER membranes. DCA is an ER-targeting, polarity-responsive NIR ratiometric probe, with its p-toluenesulfonamide group responsible for ER localization; its sensitivity to polarity relies on its donor-π-acceptor (D-π-A) structure, where aniline acts as the donor and dicyanomethylene acts as the acceptor, driving an intramolecular charge transfer (ICT) process upon excitation. In environments with low polarity, such as the closely packed, low water content ERₒ phase of ER membranes, DCA emits at a shorter wavelength, while in high polarity environments like the loosely packed, higher water content ERd phase, ICT leads to a red-shifted emission, allowing discrimination of the two phases via dual NIR emission colors and ratiometric imaging. Ex/Em = 488/570–620 nm and 488/665–735 nm; additional excitation/emission pairs include Ex/Em = 488/631 nm in low polarity 1,4-dioxane and Ex/Em = 488/677 nm in 1,4-dioxane with 30% water, the higher polarity condition. It shows a large Stokes shift of ~170 nm, and pH, viscosity, and biologically relevant species including Cys, GSH, H₂O₂, and metal ions do not exert marked interference on its fluorescence spectra[1].

NSC339614 potassium is a selective GluN1/GluN2C and GluN1/GluN2D receptor enhancer with the activity of enhancing neuronal responses to specific NMDA receptors. NSC339614 potassium can selectively enhance the signaling of GluN1/GluN2C and GluN1/GluN2D receptors without affecting other NMDA receptors. The mechanism of action of NSC339614 potassium does not compete with agonists of L-glutamate or glycine, nor does it depend on membrane potential. The activity of NSC339614 potassium depends on the specific structure of the agonist ligand binding domain, showing its potential as a novel pharmacological agent for studying the function of NMDA receptor subtypes and providing new lead compounds for a variety of neurological diseases .
