TAK 438 xC4H4O4 is a useful organic compound for research related to life sciences and the catalog number is T66985.

K 41498 is a selective peptide antagonist targeting both corticotropin-releasing factor receptor 2α (CRF2α) and CRF2β, demonstrating high affinity with Kis of 0.66 and 0.62 nM, respectively, in HEK293 cells expressing these human receptors. Its selectivity is evident as it exhibits a significantly reduced affinity for CRF1 receptor (Ki = 425 nM in HEK293 cells expressing the human CRF1 receptor). Additionally, K 41498, when administered intravenously at 1.84 µg/animal, effectively mitigates urocortin-induced hypotension in rats. Furthermore, its intrathecal delivery ranging from 0.075 to 0.5 µmol/animal significantly lowers the mechanical paw withdrawal threshold in a rat model, indicating its potential utility in managing nociception triggered by complete Freund's adjuvant.

K41498 acetate, an analogues of antisauvagine-30 (aSvg-30), inhibits sauvagine-stimulated cAMP accumulation in hCRF2α- and hCRF2β-expressing cells. K41498 acetate is a potent and highly selective antagonist CRF2 receptor with Ki values of 0.66 nM, 0.62 nM and 425 nM for human CRF2α, CRF2β and CRF1 receptors respectively.

Proteinase K (Protease K) is a non-specific serine protease that can tolerate changes in SDS, urea, pH (4-12), salt concentration, and temperature. Proteinase K hydrolyzes a wide range of peptide bonds and is used for protein digestion.

1-((3R,4S)-3-hydroxy-2,2-dimethyl-6-(phenylsulfonyl)chroman-4-yl)pyrrolidin-2-one is an isomer of Rilmakalim, a potassium channel opener (PCO), which can activate ATP-sensitive K+ channels in the heart or other tissues

PF-04753299 is a potent and selective inhibitor of UDP-3-O-(R-3-hydroxymyristol)-N-acetylglucosamine deacetylase (LpxC), demonstrating bactericidal effects against gonococcal isolates and exhibiting inhibitory activity against E. coli, P. aeruginosa, and K. pneumoniae, with minimum inhibitory concentration (MIC) 90 values of 2 μg ml, 4 μg ml, and 16 μg ml, respectively. This compound is utilized in researching gram-negative bacterial infections [1].
