Tenapanor is an inhibitor of the sodium-proton (Na(+)/H(+)) exchanger NHE3 and reduces sodium absorption in the GI tract, thus increasing intestinal fluid. Ardelyx has completed Phase 3 development of tenapanor for the treatment of irritable bowel syndrome with constipation (IBS-C) and submitted a new drug application to the U.S. Food and Drug Administration for the treatment of patients with IBS-C. In addition, tenapanor successfully completed phase III clinical trial for the treatment of hyperphosphatemia in people with end-stage renal disease who are on dialysis and RDX013, a potassium secretagogue program for the potential treatment of high potassium, or hyperkalemia, a problem among certain patients with kidney and/or heart disease.
Siponimod (BAF312) is a dual agonist at the sphingosine-1 phosphate receptors, S1PR1 and S1PR5. The S1P receptor is commonly found on the surface of specific cells residing in the central nervous system (CNS), that are responsible for causing CNS damage that drives loss of function in secondary progressive multiple sclerosis (SPMS). Siponimod (BAF312) enters the brain and by binding to these specific receptors, may prevent the activation of these harmful cells, helping to reduce the loss of physical and cognitive function associated with SPMS.

Cenobamate (also known as YKP3089) is a small molecule sodium channel blocker in development for the treatment of partial-onset seizures in adult patients. In mice and rats, Cenobamate displayed an anticonvulsant activity in the maximal electroshock test and prevented seizures induced by chemical convulsants such as pentylenetetrazol and picrotoxin. In addition, Cenobamate was reported to be effective in two models of focal seizure, the hippocampal kindled rat and the mouse 6 Hz psychomotor seizure models. Two completed adequate and well-controlled clinical studies demonstrated a significant reduction in focal seizures with Cenobamate in patients with epilepsy, and a long-term open-label phase 3 safety clinical trial is currently ongoing. Cenobamate is considered a new generation antiepileptic therapy and clinical trials have shown that it may be more effective and safer than existing drugs. If licensed, Cenobamate will offer a new adjunctive treatment option for patients with partial focal epilepsy.

Lusutrombopag (trade name Mulpleta) is an orally bioavailable, small molecule thrombopoietin (TPO) receptor agonist being developed by Shionogi for chronic liver disease (CLD) patients with thrombocytopenia prior to elective invasive surgery. Lusutrombopag acts selectively on the human TPO receptor and activates signal transduction pathways that promote the proliferation and differentiation of bone marrow cells into megakaryocytes, thereby increasing platelet levels. In September 2015, Lusutrombopag received its first global approval in Japan for the improvement of CLD-associated thrombocytopenia in patients scheduled to undergo elective invasive procedures. Oral Lusutrombopag is rapidly absorbed, with a median time to maximum serum concentration (Tmax) of 3.8–4.0 h in healthy subjects administered single doses of oral Lusutrombopag 1, 2 or 4 mg, and 6 h in CLD patients with thrombocytopenia administered oral Lusutrombopag 3 mg once daily for 7 days. The major metabolic pathway for Lusutrombopag appears to be omega- and beta-oxidation. Lusutrombopag is a substrate of breast cancer resistance protein and P-glycoprotein, according to in vitro data.

Lofexidine is newly FDA approved in the United States under the brand name LUCEMYRA for the treatment of opioid withdrawal symptoms in adults. Lofexidine acts as an agonist to α2 adrenergic receptors. These receptors inhibit adenylyl cyclase activity, leading to the inhibition of the second messenger, cyclic adenosine monophosphate (cAMP). The inhibition of cAMP leads to potassium efflux through calcium-activated channels, blocking calcium ions from entering the nerve terminal, resulting in suppression of neural firing, inhibition of norepinephrine release. Lofexidine replaces the opioid-driven inhibition of cAMP production and moderating the symptoms of opioid withdrawal.

Lotilaner is a member of the isoxazoline family, a novel class of parasiticides that targets the nerve receptors of ticks and fleas. This veterinary medicinal product provides immediate and persistent killing activity for 1 month for fleas (Ctenocephalides felis and C. canis) and ticks (Rhipicephalus sanguineus, Ixodes ricinus, I. hexagonus and Dermacentor reticulatus). The veterinary medicinal product can be used as part of a treatment strategy for the control of flea allergy dermatitis. During clinical testing, no interactions between Lotilaner chewable tablets and routinely used veterinary medicinal products were observed.
Revefenacin (trade name Yupelri is a long-acting muscarinic antagonist developed by Mylan Ireland ltd for the treatment of chronic obstructive pulmonary disease (COPD). It has similar affinity to the subtypes of muscarinic receptors M1 to M5. In the airways, it exhibits pharmacological effects through inhibition of M3 receptor at the smooth muscle leading to bronchodilation. The competitive and reversible nature of antagonism was shown with human and animal origin receptors and isolated organ preparations. In preclinical in vitro as well as in vivo models, prevention of methacholine- and acetylcholine-induced bronchoconstrictive effects was dose-dependent and lasted longer than 24 hours.
Gilteritinib, also known as ASP2215, is a potent FLT3/AXL inhibitor, which showed potent antileukemic activity against AML with either or both FLT3-ITD and FLT3-D835 mutations. In in vitro, among the 78 tyrosine kinases tested, Gilteritinib inhibited FLT3, LTK, ALK, and AXL kinases by over 50% at 1 nM with an IC50 value of 0.29 nM for FLT3, approximately 800-fold more potent than for c-KIT, the inhibition of which is linked to a potential risk of myelosuppression. Gilteritinib inhibited the growth of MV4-11 cells, which harbor FLT3-ITD, with an IC50 value of 0.92 nM, accompanied with inhibition of pFLT3, pAKT, pSTAT5, pERK, and pS6. Gilteritinib decreased tumor burden in bone marrow and prolonged the survival of mice intravenously transplanted with MV4-11 cells. In previous preclinical studies, gilteritinib has demonstrated superior antitumor effects when given in combination with AraC and either DNR or IDR compared with combination chemotherapy. In November 2018, the FDA approved gilteritinib for treatment of adult patients with relapsed or refractory acute myeloid leukemia (AML) with a FLT3 mutation as detected by an FDA-approved test.
Duvelisib (IPI-145), is an orally available, small-molecule, selective dual inhibitor of phosphatidylinositol 3 kinase (PI3K) δ and γ isoforms originated by Intellikine (owned by Takeda) and developed by Infinity Pharmaceuticals. Orally administered duvelisib was rapidly absorbed, with a dose-proportional increase in exposure. The compound produced a half-life of approximately 7-12 hours, following 14 days of dosing. Duvelisib exerts profound effects on adaptive and innate immunity by inhibiting B and T cell proliferation, blocking neutrophil migration, and inhibiting basophil activation. Duvelisib blockade of PI3K-δ and PI3K-γ potentially lead to significant therapeutic effects in multiple inflammatory, autoimmune, and hematologic diseases. The molecule is in phase III development as a combination therapy for patients with haematological malignancies such as chronic lymphocytic leukemia and follicular lymphoma.
Brilliant Blue G is triphenylmethane dye that was developed for use in the textile industry but is now commonly used for staining proteins in analytical biochemistry. The Bradford assay is a standard, rapid dye-binding assay that uses Brilliant Blue G to quantify the amount of protein in a solution. Brilliant Blue G also acts as a selective inhibitor of the P2X purinoceptor channel P2X7 (IC50s = 10.1 and 265 nM for rat and human P2X7, respectively). In mice, it inhibits interleukin-1β expression and reduces neurological injury secondary to traumatic brain injury. Brilliant Blue G was used to prepare the protein reagent for the determination of protein content of the collagenase enzyme isolated from fish waste. It may be employed as a stain for the internal limiting membrane (ILM) for the macular hole (MH) and epiretinal membrane (ERM) surgery.
