14S(15R)-EET	Others	Others
14S(15R)-EET is an endogenous epoxytrienoic acid derivative that mainly exists in rat organs. By studying its metabolic process, it was found that its stereoselective hydration and formation of chiral diols were significantly affected by epoxidase. Different 14,15-EET enantiomers showed different regions and stereochemistry of hydration reactions, among which 14(R),15(S)-EET showed specific hydration for C15. These findings reveal the important role of epoxidase in the metabolism of endogenous EETs, and the differences in enzyme affinity and reaction rate for individual EET enantiomers may lead to their stereoselective metabolism .

HY-121129

Eticlopride FLB-131	Dopamine Receptor	Neurological Disease
Eticlopride, a potent and selective D2 receptor antagonist, was investigated in rats with extensive dopamine denervation induced by 6-hydroxydopamine. Daily injections of eticlopride over 21 days increased D2 receptor density in intact brain regions but did not further augment already increased densities in denervated areas. Despite receptor density changes, functional sensitivity remained evident, as shown by contralateral rotations induced by D2 agonist quinpirole during wash-out periods. The study suggests that chronic D2 receptor blockade and dopamine denervation may share a common mechanism in upregulating D2 receptor density, contrary to previous reports suggesting additive effects of denervation and antagonist treatment .

Meropenem-vaborbactam Carbavance	Others	Infection
Meropenem-vaborbactam is an antibiotic against nonfermenting Gram-negative clinical isolates, including Enterobacteriaceae isolates with resistant and carbapenemase genotypes. The susceptibility of Meropenem-vaborbactam (at an inhibitory concentration of 8 μg/ml) and comparators was tested against 14,304 nonfermenting Gram-negative clinical isolates collected worldwide in 2014 by reference broth microdilution. Carbapenemase-encoding genes were screened by PCR and sequencing. At concentrations of ≤1 and ≤2 μg/ml, Meropenem-vaborbactam inhibited 99.1 and 99.3% of the 10,426 Enterobacteriaceae isolates tested, respectively, while Meropenem inhibited 97.3 and 97.7% of these isolates at the same concentrations. For isolates displaying carbapenem-resistant Enterobacteriaceae (CRE) (n = 265), multiagent-resistant (MDR) (n = 1,210), and extensively agent-resistant (XDR) (n = 161) phenotypes, meropenem-vaborbactam had MIC50/90 values of 0.5/32, 0.03/1, and 0.5/32 μg/ml, respectively, while meropenem activity was 16/>32, 0.06/32, and 0.5/32 μg/ml, respectively. Among all geographic regions, activity was highest in the United States against CRE and MDR isolates (MIC50/90, 0.03/1 and 0.03/0.12 μg/ml, respectively). Meropenem-vaborbactam was highly active against 135 KPC-producing isolates, with all isolates inhibited at concentrations ≤8 μg/ml (133 isolates were inhibited at concentrations ≤2 μg/ml). The combination had limited activity against isolates producing metallo-β-lactamases (including 25 NDM-1 and 16 VIM producers) and/or oxocephalosporinases (27 OXA-48/OXA-163 producers), which were mainly found in the Asia-Pacific region and some European countries. Meropenem-vaborbactam had activity comparable to meropenem against Pseudomonas spp., Acinetobacter spp., and Clostridium amylovora. Meropenem-vaborbactam was active against a global collection of contemporary Enterobacteriaceae isolates, and the combination had greater activity against CRE isolates and KPC producers than did meropenem and most comparators, which are often multiagent-resistant.

Tibetan medicine, as one of the treasures of traditional Chinese medicine, carries the profound cultural heritage of the Tibetan people and their unique understanding of health. Tibet is the birthplace of Tibetan medicine, and its plateau climate and unique ecological environment have nurtured its rich medicinal resources. Among them, cordyceps, saffron and snow lily are favored by people for their excellent medicinal value and unique growth characteristics. Tibetan medicine, with its profound heritage, plays a crucial role in the management of diseases that are unique to high-altitude regions, such as altitude stress. It facilitates a swifter adaptation to high-altitude conditions and mitigates the symptoms of altitude sickness by meticulously recalibrating the internal environment within the human body. For rheumatic diseases, cardiovascular diseases, etc., Tibetan medicine has also shown its remarkable effect.

Antiparasitic Compound library

489 compounds

A parasite is an organism that lives on or in a host organism and gets its food from or at the expense of its host. Parasites of humans include protozoans, helminths, and ecto-parasites (organisms that live on the external surface of a host). They are responsible for many diseases and are transmitted to their hosts most often through the ingestion of contaminated food, water or through the bite of an arthropod (e.g., a fly or tick), which can act as an intermediate host and as a vector. Parasitic diseases of humans are a major global health problem causing significant morbidity and mortality, especially in developing countries. Each year there are hundreds of millions of people infected with disease-causing parasites, particularly in tropical and subtropical regions of the world, resulting in an estimated one million deaths. Therefore, there is a dire need of novel anti-parasitic drugs.

MCE has a unique collection of 489 compounds with validated anti-parasitic activity which offer researchers an opportunity to screen novel anti-parasitic targets.
