CR-1 is a ratiometric photoacoustic (PA) probe for in-situ real-time imaging of Zn 2+ in deep living tissues. CR-1 is formed by coupling the near-infrared cyanine dye IR825 with the Zn 2+ ligand tris (2-pyridylmethyl) amine (TMPA). Upon binding to Zn 2+, the five N atoms on TMPA coordinate with Zn 2+, leading to double bond rearrangement of IR825 and attenuation of its π-electron conjugated system. The absorption peak of CR-1 blue-shifts from 710 nm to 532 nm, enabling quantitative detection of Zn 2+ via the PA532/PA710 ratio. Free CR-1 generates a strong PA signal at 710 nm, while CR-1 bound to Zn 2+ produces a strong PA signal at 532 nm .

Photosensitizer

Research Areas:  

Cancer

Meso-tetraphenylchlorin (TPCS2a) is a photosensitizer with poor water solubility, which limits its use in the blood circulation. However, TPCS2a@NPs nanoparticles can be prepared based on polylactic-co-polyethylene glycol acid (PLGA) polymer core loaded with TPCS2. Such nanoparticles can be coated with mesenchymal stem cell-derived plasma membranes (mMSCs) to form mMSC-TPCS2a@NPs, which prolongs blood circulation time and improves tumor targeting ability. Compared with uncoated TPCS2a@NPs, mMSC-TPCS2a@NPs can reduce macrophage uptake by 54% to 70% under different conditions. Both nanoparticle forms are effectively accumulated in MCF7 and MDA-MB-231 breast cancer cells, while uptake in normal breast epithelial cells MCF10A is significantly lower .

2,256 compounds

At the forefront of innovative drug discovery, every medicinal chemist faces the challenge of rapidly identifying high-quality hit compounds from vast repositories of chemical resources.

The MCE Natural Product Diversity Scaffold Library is the result of a streamlined optimization process built upon our existing natural product collection. Adhering to the rigorous selection principle of "retaining only one representative compound per BMS scaffold", we have concentrated the diversity of thousands of compounds into a high-value, low-redundancy core set containing 2,256 compounds. All compounds are derived from natural sources, inheriting their inherent advantages of structural complexity and drug-likeness. By eliminating redundancy, the library size is significantly reduced without any compromise to chemical diversity. This approach effectively lowers the cost and time required for primary screening while simplifying downstream data analysis and structure-activity relationship (SAR) studies.

Covalent inhibitors are small molecules that can bind specifically to target proteins through covalent bonds and inhibit their biological functions. Although for a long time, covalent targeting has been playing a subordinate role in drug discovery, with an increasing number of reports on successful clinical applications of such drugs, the potential of these agents is now being acknowledged. Currently, cysteine is the most common covalent amino acid residue in a variety of covalent drugs, and various warheads have been developed that can react with cysteine, providing the key building blocks for covalent drugs to form covalent bonds.

To meet the development needs of covalent inhibitors targeting cysteine, MCE has designed a unique collection of 5,267 compounds with different covalent warheads that target cysteine. The MCE Cysteine Targeted Covalent Library is designed using the following covalent warheads: Acrylamides, Propiolic acid ester, Dimethylamine functionalized acrylamides, Chloroacetamides, Acrylonitrile, 2-Cyanoacrylamide, Aziridine, Haloacetamide, etc.

DNA is prone to numerous forms of damage that can injure cells and impair fitness. Cells have developed an array of mechanisms to repair these injuries. Proliferating cells are especially vulnerable to DNA damage due to the added demands of cellular growth and division. Cell cycle checkpoints represent integral components of DNA repair that coordinate cooperation between the machinery of the cell cycle and several biochemical pathways that respond to damage and restore DNA structure. By delaying progression through the cell cycle, checkpoints provide more time for repair before the critical phases of DNA replication, when the genome is replicated, and of mitosis, when the genome is segregated. Loss or attenuation of checkpoint function may increase spontaneous and induced gene mutations and chromosomal aberrations by reducing the efficiency of DNA repair.

MCE owns a unique collection of 3,522 cell cycle/DNA damage-related compounds which can be used in the research of the same.

Lys-VBOD is a Fluorescent probe for lysosomal viscosity monitoring and live cell imaging. Its detection mechanism depends on viscosity: increased viscosity restricts the twisting of the double bond between the indole and BODIPY fluorophore, as well as the rotation of the single bond between quinoline and BODIPY, which reduces non-radiative decay and leads to enhanced fluorescence intensity in high viscosity environments; it also features a morpholine group that provides lysosome-targeting properties, allowing it to localize to lysosomes for viscosity detection. The probe has excitation/emission wavelengths of Ex/Em = 602/637 nm, and its fluorescence intensity shows a good linear relationship with log-transformed viscosity values. Lys-VBOD is stable across a wide pH range of 5.35 to 10.74, is not affected by macromolecules and proteins like BSA, has a fluorescence lifetime that increases with viscosity, and can visualize real-time lysosomal viscosity changes in live cells under Dexamethasone (HY-14648) stimulation[1].

Rare diseases are an important public-health issue and a challenge for the medical community. Most rare diseases are genetic disorders, which are often severely disabling, substantially affect life expectancy, and impair physical and mental abilities. Currently, there are about 7,000 identified rare diseases, together affecting 10% of the population. However, fewer than 6% of all rare diseases have an approved treatment option, highlighting their tremendous unmet needs in drug development. The process of repurposing drugs for new indications, compared with the development of novel orphan drugs, is a time-saving and cost-efficient method resulting in higher success rates, which can therefore drastically reduce the risk of drug development for rare diseases.

MCE carefully collects a unique of 1,900 compounds studied in preclinical, clinical trials or approved used in rare diseases treatment. MCE rare diseases drug library is a useful tool for the research of rare diseases. All compounds can provide corresponding indications for rare diseases.

The occurrence of diseases is often associated with multiple targets and pathways, and the factors of disease formation are complex and diverse, so the development of more powerful drugs is needed. According to statistics, 21% of the FDA-approved drugs in 2015-2017 were multi-target compounds. Multi-target compounds refer to a drug targeting multiple disease-related targets or multiple subtypes of a target. Multi-target compounds can be applied to drug screening or targeted ligand design. Because the targets of such compounds are diverse and clear, they have the characteristics of saving time and drug cost during the mechanism research of new drug research and development. In addition, due to the diversity of drug targets, multiple strategies can be applied to pharmacological studies.

MCE supplies a unique collection of 7,362 multi-target compounds that targets two or more different targets or different subtypes of the same target. MCE Multi-Target Compound Library can be used for target protein ligand screening or drug development.

Neurodegenerative diseases are incurable and life-threatening conditions that result in progressive degeneration and/or death of nerve cells. Some common neurodegenerative diseases include Alzheimer’s Disease (AD), Parkinson’s Disease (PD), Motor Neuron Disease (MND), Huntington’s Disease (HD), Spino-Cerebellar Ataxia (SCA), Spinal Muscular Atrophy (SMA), and Amyotrophic Lateral Sclerosis (ALS). Because the pathophysiology of neurodegenerative disorders is generally poorly understood, it is difficult to identify promising molecular targets and validate them. At the same time, about 85% of the drugs fail in clinical trials. Therefore, validating new targets and discovering new drugs to mitigate neurodegenerative disorders is need of the hour.

MCE offers a unique collection of 3,759 compounds with anti-Neurodegenerative Diseases activities or targeting the unique targets of neurodegenerative diseases. MCE Neurodegenerative Disease-related Compound Library is a useful tool for exploring the mechanism of neurodegenerative diseases and discovering new drugs for neurodegenerative diseases.
