GlyH-101 is a cell-permeable glycinyl hydrazone compound that blocks CFTR with Ki of 1.4 uM.

Flufenamic acid-d4 is intended for use as an internal standard for the quantification of flufenamic acid by GC- or LC-MS. Flufenamic acid is a non-steroidal anti-inflammatory drug (NSAID) and COX inhibitor (IC50s = 3 and 9.3 µM for human COX-1 and COX-2, respectively). Flufenamic acid inhibits TNF-α-induced increases in COX-2 levels and NF-κB activation in HT-29 colon cancer cells in a concentration-dependent manner. It inhibits calcium influx induced by fMLP or A23187 in human polymorphonuclear leukocytes (PMN) with IC50 values of 29 and 14 µM, respectively. Flufenamic acid also activates various ion channels, including transient receptor potential canonical 6 (TRPC6) and the large-conductance calcium-activated potassium channel (KCa1.1). It also inhibits various ion channels, including TRPC3 and the cystic fibrosis transmembrane conductance regulator (CFTR). Flufenamic acid (20 mg kg) reduces increases in intestinal fluid secretion and intestinal barrier disruption in mice ......

PAT1inh-B01, a selective SLC26A6 inhibitor, impedes PAT1 (a Cl- HCO3- exchanger) activity, with an IC50 of 350 nM, effectively inhibiting anion exchange. It also obstructs fluid absorption in the small intestine and is utilized in the study of small intestinal hyposecretory disorders [1].

PAT1inh-A0030 is a selective inhibitor of PAT1 (SLC26A6) with an IC 50 value of 1.0 μM. It inhibits fluid absorption in the ileum of wild-type and cystic fibrosis (CF) mice (CftrdelF508 delF508) in a closed-loop model of intestinal fluid absorption and can be used in the study of intestinal diseases related to CF [1].

Lubiprostone (hemiketal) (RU-0211 (hemiketal)), a selective activator of the chloride channel 2 (CLCN2), facilitates the treatment of chronic idiopathic constipation and opioid-induced constipation. It functions by enhancing CLCN2 channel activity, which boosts chloride ion secretion in the intestines, subsequently increasing fluid secretion and improving intestinal peristalsis. Additionally, Lubiprostone (hemiketal) may be utilized in research related to chronic constipation and cancer.

Tilifodiolide exerts in vitro and in vivo anti-inflammatory activity and in vivo antinociceptive effects. Tilifodiolide exerted antidiarrheal activity by decreasing the intestinal fluid accumulation and vasorelaxant effects mediated by nitric oxide and cyclic guanosine monophosphate, it also showed anxiolytic and antidepressant effects by the partial involvement of gamma-Aminobutyric acid (GABA) receptors and the possible participation of α2-adrenoreceptors, respectively.
