Descripciòn

Theobromine is a methylxanthine found in cacao beans which can inhibit adenosine receptor A1 (AR1) signaling.

IC50 & Target

AR1[1]
In Vitro

Theobromine, at concentrations above 25 μM, decreases lipid accumulation in these cells. Cell viability is not affected by Theobromine. Theobromine, at concentrations above 25 μM, suppresses protein expression of PPARγ, C/EBPα and adipogenic genes. The mRNA levels of these genes are also decreased by Theobromine[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

Body weights are lower in the Theobromine group than in the vehicle group. In addition, Theobromine suppresses gains in weight of epididymal and perirenal adipose tissues. The mean adipocyte area is smaller in the Theobromine group than in the vehicle group[1]. Theobromine group shows lower counts than the other groups when considering the number of bacteria per fecal weight (p=0.021 and p=0.055 compare to the reference (RF) and the cocoa (CC) groups, respectively). The Theobromine diet leads to higher pH values than those found after the RF and CC diets. Fecal concentrations of lactic acid are not significantly affected by the experimental diets (4.26±1.54 mM in RF group; 1.96±0.41 mM in CC group; 2.69±0.73 mM in Theobromine group)[2].

3T3-L1 preadipocytes are pre-incubated with MG132 (10 μM) for 30 min, followed by incubation with IBMX in the presence or absence of Theobromine (25 μM) for 8 h. The cells are lysed in denaturing cell extraction buffer (50 mM Tris-HCl, pH 7.5, containing 70 mM β-mercaptoethanol and 2% SDS) at 95°C for 10 min. The cell lysates are diluted 20 fold with dilution buffer (20 mM Tris-HCl, pH 7.5, containing 150 mM NaCl, 1 mM EDTA, 1mM EGTA, 1% TritonX-100, 2.5 mM sodium pyrophosphate and protease inhibitor cocktail) and centrifuged at 20,000 g for 30 s. The supernatant is incubated with rabbit polyclonal anti-C/EBPβ IgG, anti-FLAG IgG or control IgG at 4°C overnight, followed by incubation with 30 μL protein G-Sepharose resin at 4°C for 1 h. The resin is washed with lysis buffer three times and proteins bound to the resin are separated by SDS-PAGE and analyzed by western blotting[1].

[2]

Lewis rats (3 week old) are used in this study. The rats are randomly distributed into three dietary groups (n=7 per group): the reference (RF) group ingested standard diet AIN-93M, the cocoa (CC) group ingested a standard diet with 10% of natural Forastero cocoa containing 0.25% Theobromine, and the Theobromine (TB) group ingested a standard diet including 0.25% of Theobromine, i.e. the content of Theobromine presents in the CC diet[2].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
