it 139

ELB-139 is a GABAA receptor agonist that can be used to study depression and epilepsy.

Compound 6h (Anticancer Agent 139) exhibits potent anticancer activity, engaging in a π-cationic interaction with Lys352 of Tubulin and demonstrating high efficacy against SNB-19, OVCAR-8, and NCI-H460 with PGIs of 86.61, 85.26, and 75.99, respectively. Moreover, it shows moderate activity against a range of other cancer cell lines — HOP-62, SNB-75, ACHN, NCI/ADR-RES, 786-O, A549/ATCC, HCT-116, and MDA-MB-231 — with PGIs between 51.88 and 67.55 [1].

Antibacterial agent 139 exhibits antibacterial activity specifically targeting Gram-positive bacteria, including resistant strains such as MRSA (anti-MRSA), VISA (anti-VISA), and LRSE (anti-LRSE). It operates by depolarizing the bacterial cell membrane [1].

[Leu144,Arg147]-PLP (139-151) is a mutated fragment of the myelin proteolipid protein (PLP), featuring substitutions of tryptophan to leucine and histidine to arginine at positions 144 and 147, respectively. Immunizing mice with this peptide (50 µg) mixed in complete Freund’s adjuvant (CFA) elevates IL-4 levels in the spleen. While it suppresses Th1 cell activation in vitro, it does not do so in vivo; instead, it promotes the development of regulatory T cells. Preimmunization with [Leu144, Arg147]-PLP (139-151) postpones the onset of experimental autoimmune encephalomyelitis (EAE) triggered by encephalitogenic peptides from PLP (178-191), myelin oligodendrocyte glycoprotein (MOG) (92-106), or myelin basic protein (MBP) in mice.

DK-139 is an inhibitor of NF-kappaB-mediated GROalpha expression, suppressing the TNFalpha-induced invasive capability of MDA-MB-231 human breast cancer cells.

Plp(139-151) trifluoroacetate is a useful organic compound for research related to life sciences and the catalog number is T64674.

[SER140]-PLP(139-151) acetate is a peptide fragment from myelin proteolipid protein (PLP).

TD139 is an inhaled galectin-3 inhibitor with a dissociation constant (Kd) of 14 nM.

NKP-1339 (IT-139) induces G2/M cell cycle arrest, blockage of DNA synthesis, and induction of apoptosis via the mitochondrial pathway.

BOLD-100 free base (NKP-1339; IT-139), a ruthenium-based anticancer agent, inhibits stress-induced GRP78 upregulation, thus disrupting endoplasmic reticulum (ER) homeostasis. This action induces ER stress and unfolded protein response (UPR), interfering with the intricate relationship between ER-stress response, lysosome dynamics, and autophagy execution.

GPR139 agonist-2 (compound 20a), a potent GPR139 agonist with an EC50 of 24.7 nM, has demonstrated efficacy in rescuing social interaction deficits and alleviating cognitive deficits in murine schizophrenia models, indicating its potential in antischizophrenia drug research [1].

[SER140]-PLP(139-151) is a polypeptide fragment derived from the myelin-associated lipid protein.

PU139 is a novel inhibitor of histone acetyltransferase (HAT).

WRR139, a peptide vinyl sulfone, plays a role in disease processes including inflammation and cancer, and acts as an inhibitor of cytosolic enzyme N-glycanase 1 (NGLY1) and Nrf1. Moreover, WRR139 amplifies the cytotoxic effects of Carfilzomib on cancer cells [1].

PLP (139-151), an amino acid residue from positions 139 to 151 of myelin proteolipid protein (PLP), is utilized to induce the relapsing-remitting (RR)-EAE model.

[SER140]-PLP(139-151) (TFA) is a polypeptide fragment of the myelin lipid protein.

PLP (178-191), an immunodominant encephalitogenic epitope from the proteolipid protein (PLP) fragment spanning amino acids 178 to 191, plays a pivotal role in SJL mice. It initiates disease onset earlier compared to the other major encephalitogenic epitope, PLP (139-151), though both epitopes result in similar incidence, severity, and histologic characteristics.

J5 peptide, an MBP inhibitor, competitively inhibits the binding of MBP 85-99 to HLA-DR2, and mitigates PLP 139-151/MBP 85-99-induced experimental autoimmune encephalomyelitis (EAE) in mice. It is utilized in research pertaining to inflammatory and immune diseases [1].

Brazikumab (AMG 139), a human IgG2 monoclonal antibody, selectively targets the p19 subunit of IL-23 with a dissociation constant (K D) of 0.138 nM, indicating high affinity for human IL-23. It is employed in Crohn's disease research [1].

WZ4003, a highly selective NUAK kinase inhibitor, is with IC50 of 20 nM and 100 nM for NUAK1 and NUAK2, respectively. It is no significant inhibition on 139 other kinases.
