an 168

Compound D16 (Anticancer agent 168) is an inhibitor of DNA2 that induces apoptosis and cell-cycle arrest predominantly in the S-phase. It demonstrates anticancer efficacy and can counteract chemotherapy resistance in cancers harboring mutant p53 [1].

CB 168 is a potent selective aminoacylaminoaryl tetrazole inhibitor targeting isoleucine tRNA synthetase (IleRS).

Tat-peptide 168-189, a cell-permeable, Tat-labeled fusion peptide derived from residues 168-189 of rat G3BP1, features the HIV Tat sequence at its least conserved terminus to enhance cellular uptake. It serves as the negative control for Tat-peptide 168-189 TFA, which promotes axon growth and neurite proliferation [1].

BL-1020 Mesylate (CYP-1020 Mesylate) is an orally available GABA A receptor agonist and D2 antagonist that decreases dopamine activity and enhances GABAA activity.BL-1020 Mesylate has been used in the study of schizophrenia, Alzheimer's disease, and bi-directional cognitive impairment.

ST-168 is a potent inhibitor of PI3K and MEK. ST-168 displays improved PI3K and MEK1 isoform inhibition. ST-168 demonstrated a 2.8-, 2.7-, 23-, and 2.5-fold improved inhibition toward the PI3Kα, PI3Kβ, PI3Kδ, and PI3Kγ isoforms and a 2.2-fold improvement

BF-168 is a candidate probe for PET and specifically recognizes both neuritic and diffuse plaques (Ki: 6.4 nM for Aβ1-42).

(R)-ADX-47273 is a potent positive allosteric modulator of mGluR5, with an EC50 of 168 nM for potentiation.

Vulolisib is an orally active and potent inhibitor of phosphatidylinositol 3 kinase (PI3K), acting on PI3Kα (IC50: 0.2 nM), PI3Kβ (IC50: 168 nM), PI3Kγ (IC50: 90 nM), PI3Kδ (IC50: 49 nM). activity and exhibits anti-proliferative activity against cancer cells.

O-Benzylhydroxylamine is a building block.1,2It has been used in the synthesis of β-lactam inhibitor precursors and fluoroquinolone derivatives with antibiotic activity. 1.Bellettini, J.R., and Miller, M.J.A short synthesis of an important precursor to a new class of bicyclic β-lactamase inhibitorsTetrahedron Lett.38(2)167-168(1997) 2.Asadipour, A., Moshafi, M.H., Khosravani, L., et al.N-substituted piperazinyl sarafloxacin derivatives: synthesis and in vitro antibacterial evaluationDaru.26(2)199-207(2018)

Neihulizumab (ALTB-168), an immune checkpoint agonistic antibody, targets and binds to human CD162 (PSGL-1), resulting in the downregulation of activated T-cells. It is utilized in research aimed at treating steroid-refractory acute graft-versus-host disease (SR-aGVHD), psoriasis, psoriatic arthritis, and ulcerative colitis [1].

PMX-205 is a cyclic hexapeptide that acts as a potent antagonist of C5a receptor (C5aR; IC50= 31 nM).1It is orally active and blocks inflammatory signaling and symptoms in animal models of colitis and allergic asthma.2,3PMX-205 is also brain penetrant and reduces neuroinflammation and neurodegeneration in an animal model of Alzheimer's disease.4 1.March, D.R., Proctor, L.M., Stoermer, M.J., et al.Potent cyclic antagonists of the complement C5a receptor on human polymorphonuclear leukocytes.

Oosporein is a mycotoxin that has been found inBeauveriaand has diverse biological activities.1,2It is cytotoxic to Sf9 and Sf21 insect cells with 50% cytotoxic concentration (CC50) values of 4.23 and 10.43 μM, respectively.3Oosporin induces lethality in day-old cockerels (LD50= 6.12 mg kg).4It inhibits Na+ K+-, Ca2+-, and Mg2+-ATPase activities by 27, 52, and 100%, respectively, in equine erythrocyte ghosts when used at a concentration of 200 μg ml.2Oosporein inhibits herpes simplex 1 (HSV-1), but not HeLa cell orE. coli, DNA polymerase (IC50s = 75, 610, and >700 μM, respectively).5It is active against the bacteriumS. pneumoniae(MIC = 32 μg ml) and the plant pathogenic fungusP. infestans(MIC = 16 μM).1,6 1.Wainwright, M., Betts, R.P., and Teale, D.M.Antibiotic activity of oosporein from Verticillium psalliotaeTrans.
