2',7'-Difluorofluorescein (Oregon green 488) is a fluorescein derivative and a pH-sensitive fluorescent probe (pKa ~4.7). Upon excitation at 488 nm, 2',7'-Difluorofluorescein exhibits pH-sensitive fluorescence intensity through the formation of dianions, while its pH sensitivity decreases under excitation at 450 nm, allowing its use in ratiometric pH analysis. 2',7'-Difluorofluorescein can be used for the quantitative analysis of pH values in the range of 2-7 in submicron aerosol particles. 2',7'-Difluorofluorescein undergoes buffer-mediated and buffer-free excited-state proton transfer between different protonated forms, and its cationic form undergoes rapid excited-state deprotonation. 2',7'-Difluorofluorescein is resistant to photodegradation, maintains stable absorption and fluorescence properties within the physiological pH range, and serves as a fluorescent protein label, a component of Ca 2+ indicators, a fluorescent imaging agent, and an anisotropy probe .

Resistance refers to the decrease in the effectiveness of drugs in treating diseases or symptoms. Due to the increasing global antibiotic resistance, it may threaten our ability to treat common infectious diseases. Drug resistance is also the main cause of chemotherapy failure in malignant tumors. In approximately 50% of cases, drug resistance exists even before chemotherapy begins. There are many mechanisms of anticancer drug resistance, including increased protein expression that leads to drug removal, mutations in drug binding sites, recovery of tumor protein production, and pre-existing genetic heterogeneity in tumor cell populations. In addition, the issue of drug resistance seems to have affected the development of new anticancer drugs. Drug resistance may be caused by various conditions, such as mutations, epigenetic modifications, and upregulation of drug efflux protein expression. Overcoming multidrug resistance in cancer treatment is becoming increasingly important.

MCE designs a unique collection of 722 anti-drug-resistant compounds. It is a good tool to be used for research on cancer and other diseases.
