c3a

C3a Receptor Agonist (C3a receptor agonist 1) binds the G protein-coupled C3a receptors (C3aRs) in the immune system complement pathway. Activation of C3aR prevents neutrophils from being mobilized in a model of intestinal ischemia-reperfusion injury. C3aRs are expressed on neural progenitor cells and immature neurons in adult mice. C3a stimulates differentiation of neural progenitor cells in vitro.

C3a (70-77) is an octapeptide that corresponds to the COOH terminus of C3a.

SB290157 trifluoroacetate is a potent and selective antagonist of the C3a receptor, with an IC50 of 200 nM.

JR14a (5-(Bis(4-chlorophenyl)methyl)-3-methylthiophene-2-carbonyl)-l-arginine hydrochloride) is a potent antagonist of human complement C3a receptor.

C3a 70-77 acetate is the octapeptide acetate corresponding to the COOH terminus of C3a, exhibits the specificity and 1 to 2% biologic activities of C3a.

C3a 70-77 2TFA(63555-63-5(free base)) (Complement 3a (70-77)) is an octapeptide corresponding to the COOH terminus of C3a.

Complement 3a (70-77) TFA is an octapeptide that corresponds to the COOH terminus of C3a and exhibits the specificity and 1 to 2% biological activities of C3a [1] [2].

C3a (70-77) TFA (Complement 3a (70-77) TFA) is a COOH-terminal fragment of the C3a anaphylatoxin peptide.

(Trp63, Trp64)​-C3a(63-77) is a C3a synthetic analogue peptide that exhibits Ca 2+ stimulating efficacy in human neutrophils, as well as hC3aR or mC3aR expressing RBL-2H3 cells, with EC50 values of 9.5, 2.0, and 0.8 nM, respectively [1].

Boc 3 Arg is a tert-butyl carbamate-protected arginine compound. It serves as an efficient tag that induces degradation by directly targeting proteins to the 20S proteasome.

N-Nitrosonornicotine, a tobacco-specific nitrosamine, exhibits carcinogenic and mutagenic properties, and is capable of inducing micronuclei in C3A cells. Additionally, N-Nitrosonornicotine can form DNA adducts.

4-Octylphenol is an endocrine disruptor with gender-specific effects on male germ cells, significantly reducing the mitotic index and the number of spermatogonia. It also causes inflammatory damage in the gills of carp by activating the complement system through the C3a/C3a receptor (C3a/C3aR) axis and C5a/C5a receptor 1 (C5a/C5aR1) axis. Furthermore, 4-Octylphenol induces immune suppression by disrupting the balance between helper T (Th) cells 1/Th2 and regulatory T (Treg)/Th17 cells, and triggers inflammatory damage through the Toll-like receptor 7 (Toll-like Receptor (TLR))/inhibitor κBα/nuclear factor κB (TLR7/IκBα/NF-κB) pathway.

Nrf2 HO-1 Activator 3 (Compound C3a) is an activator of the Nrf2 signaling pathway that facilitates the translocation of Nrf2 into the nucleus and enhances the expression of heme oxygenase-1 (HO-1). In H9c2 cardiomyocytes subjected to H2O2 or high glucose stimulation, Nrf2 HO-1 Activator 3 inhibits the excessive expression of ROS and MDA, suppressing cell viability and colony formation, thereby exhibiting antioxidant activity.

Pantothenate Kinase Inhibitor (PANKi) is a reversible inhibitor of pantothenate kinase (PanK; IC50s = 70, 92, and 25 nM for PanK1β, PanK2, and PanK3, respectively), the rate-limiting enzyme in the synthesis of coenzyme A .1It binds to the ATP-PanK3 complex with an apparent binding constant of 300 nM and exhibits mixed-type inhibition with respect to ATP and pantothenate. PANKi inhibits CoA biosynthesis in C3A cells (IC50= 0.9 μM) with no effect on cell viability when used at concentrations up to 8 μM. PANKi (5 μM) synergizes with BSO to induce ferroptosis in PANC-1 cells and sensitizes the cells to imidazole ketone erastin-induced ferroptosis.2 1.Sharma, L.K., Leonardi, R., Lin, W., et al.A high-throughput screen reveals new small-molecule activators and inhibitors of pantothenate kinasesJ.

11β-HSD1-IN-10, a potent inhibitor of 11β-HSD1 with an IC50 value of 1.8 µM for humans, is suitable for research into obesity, hyperglycemia, and cognitive impairment.

4-Octylphenol (Standard) is the standard substance of 4-Octylphenol, and it is applicable for quantitative analysis, quality control, and related research in biochemical experiments. 4-Octylphenol is an endocrine disruptor with gender-specific effects on male germ cells, significantly reducing the mitotic index and the number of spermatogonia. It also causes inflammatory damage in the gills of carp by activating the complement system through the C3a/C3a receptor (C3a/C3aR) axis and C5a/C5a receptor 1 (C5a/C5aR1) axis. Furthermore, 4-Octylphenol induces immune suppression by disrupting the balance between helper T (Th) cells 1/Th2 and regulatory T (Treg)/Th17 cells, and triggers inflammatory damage through the Toll-like receptor 7 (Toll-like Receptor (TLR))/inhibitor κBα/nuclear factor κB (TLR7/IκBα/NF-κB) pathway.
