New Small Molecules from MCE for October 2020

New Small Molecules from MCE for October 2020

MCE (MedChemExpress) provides a wide range of lifescience biochemicals, including more than 25,000 bioactive compounds, recombinant proteins, dye reagents, peptides and natural compounds for laboratory and scientific use.


• Bacterial Inhibitor
SPR206 acetate                                 CAS No. : 2408422-41-1

SPR206 acetate is a polymyxin analog with antibiotic activity against Gram-negative pathogens, including multidrug-resistant (MDR) variants. SPR206 acetate has an anti-bacterial infection effect by interacting with the bacterium’s outer membrane. The MIC values of SPR206 acetate against Pseudomonas aeruginosa Pa14 and Acinetobacter baumannii NCTC13301 are both 0.125 mg/L.

Compound Screening Libraries



50 specific libraries for high throughput screening (HTS) and high content screening (HCS). Optimized for drug screening and new indication research.

• Parasite Inhibitor
Purfalcamine                                 CAS No. : 1038620-68-6

Purfalcamine is an orally active, selective Plasmodium falciparum calcium-dependent protein kinase 1 (PfCDPK1) inhibitor with an IC50 of 17 nM and an EC50 of 230 nM. Purfalcamine has antimalarial activity and causes malaria parasites developmental arrest at the schizont stage.

Cell Signaling Pathway

• PARP Inhibitor
RBN012759                                      CAS No. : 2360851-29-0

RBN012759 is a potent, selective and orally active inhibitor of PARP14, with an IC50 of <3 nM. RBN012759 displays 300-fold selectivity over the monoPARPs and 1000-fold selectivity over the polyPARPs. RBN012759 decreases pro-tumor macrophage function and elicits inflammatory responses in tumor explants.
