Peptides

IKKγ NBD Inhibitory Peptide is a selective inhibitor of NF-κB signaling. It functions by disrupting the interaction between the IKKγ/NEMO-binding domain and IKKα/IKKβ, effectively blocking TNF-α-induced NF-κB activation. This peptide exhibits significant anti-inflammatory properties and has potential applications in studying cerebral ischemia and its associated neurological deficits.

Acetyl-Tau Peptide (273-284) amide is an acetylated fragment of the Tau protein that acts as an inhibitor of Aβ fibrillogenesis. It effectively reduces the aggregation of Ac-Aβ(25–35)-NH2, facilitating studies on the interplay between Aβ and Tau proteins. This peptide serves as a valuable experimental tool for investigating the mechanisms underlying Alzheimer's disease and related neurodegenerative conditions.

CaMKII inhibitory peptide KIIN is a selective inhibitor of calcium/calmodulin-dependent protein kinase II (CaMKII). This peptide effectively disrupts CaMKII activity, making it a valuable tool for studying CaMKII-dependent signaling pathways. Its use in various research applications includes investigating cellular processes such as synaptic plasticity, memory formation, and cardiac function.

Polyglutamine binding peptide 1 (QBP1) is a peptide inhibitor that specifically targets polyglutamine sequences. It effectively inhibits polyQ protein aggregation in vitro and demonstrates the ability to suppress polyQ-induced cell death in cell culture models. This reagent is valuable for research focused on neurodegenerative disorders associated with polyglutamine expansion, providing insights into potential therapeutic interventions.

Cysteine peptide is a potent tyrosinase inhibitor that exhibits skin-whitening, antioxidant, and multi-regulatory properties. By inhibiting tyrosinase activity and obstructing melanin transport, it effectively reduces UV-B-induced skin erythema and pigmentation. Additionally, cysteine peptide plays a role in skin health by scavenging reactive oxygen species (ROS), mitigating oxidative stress, and promoting pheomelanin synthesis. This compound also functions as a plant signaling factor, influencing vegetative growth, development, and responses to environmental stressors.

PD 125967 is an oligopeptide renin inhibitor that specifically targets the renin-angiotensin system. It exhibits significant activity in lowering blood pressure, making it a valuable tool for cardiovascular research. This compound is useful for studying hypertension and related disorders, providing insights into the regulation of blood pressure through renin inhibition.

KSL 128114 is a potent peptide inhibitor of syntenin, targeting the PDZ1 domain with nanomolar affinity. This compound exhibits stability in human plasma and mouse hepatic microsomes, making it suitable for in vitro and in vivo studies. KSL 128114 demonstrates selective inhibition of syntenin, providing valuable insights into cellular signaling pathways and potential therapeutic applications in disorders associated with syntenin dysregulation.

ANK peptide is a selective synuclein-γ (SNCG) inhibitor that effectively disrupts the interaction between SNCG and BubR1. This interference enhances the sensitivity of breast cancer cells to antimicrotubule agents, including nocodazole and paclitaxel. ANK peptide is valuable for research into cancer biology, particularly in understanding the molecular mechanisms of drug resistance in breast cancer.

J5 peptide is a competitive inhibitor of myelin basic protein (MBP) that prevents the binding of MBP85-99 to HLA-DR2. This peptide has demonstrated efficacy in alleviating PLP139-151/MBP85-99-induced experimental autoimmune encephalomyelitis (EAE) in murine models. J5 peptide is relevant for research on inflammatory and immune diseases, particularly in studies targeting autoimmune mechanisms.
