SB-699551 is a selective and brain penetrant 5-HT5A receptor antagonist with a pK_i of 8.2 nM. SB-699551 shows high selectivity over most other 5-HT receptor subtypes, dopamine receptors, and α1B adrenoceptor. SB-699551 disrupts Gαi/o-coupled and PI3K/AKT/mTOR signaling pathways, alters CREB, ATF1, AKT, PRAS40, S6K, and FOXO1 phosphorylation in breast tumor cells. SB-699551 can be used for the research of anxiety, breast cancer, and Alzheimer's disease.

In Vitro

SB-699551 potently binds to human 5-HT_5A receptors expressed in CHO cells with a pK_i of 8.2 and exhibits ≥100-fold selectivity against most other 5-HT receptor subtypes^[1].
SB-699551 (1 μM) acts as a competitive antagonist at human 5-HT_5A receptors expressed in HEK 293 cells, with an apparent pK_B of 8.0^[1].
SB-699551 (72 h) inhibits tumorsphere formation and cell viability in HCC1954 and MCF-7 human breast tumor cell lines with IC₅₀ values ranging from 0.2 to 0.3 μM^[3].
SB-699551 inhibits tumorsphere formation in PDX-derived human breast tumor cell lines (PDX 81, PDX 18, PDX 12) with IC₅₀ values ranging from 470 nM to 775 nM, independent of subtype^[3].
SB-699551 (4 μM, 30 min; 4 μM, 5-60 min; 3-5 μM, 24 h) modulates signaling via the Gα_i/o pathway and the PI3K/AKT/mTOR axis in MCF-7 and MDA-MB-157 human breast tumor cell lines, with increased CREB phosphorylation and reduced phosphorylation of AKT and downstream targets^[3].

Stock Solution Working Solution

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
