实验参考方法

Cell experiment [1]:

Cell lines

A549, T47D, DU4475, and 22Rv1 cancer cells

Preparation method

Limited soluble in DMSO. General tips for obtaining a higher concentration: Please warm the tube at 37 ℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months.

Reacting condition

30 μM, 37 °C

Applications

OTSSP167 inhibited A549 (lung), T47D (breast), DU4475 (breast), and 22Rv1 (prostate) cancer cells with the IC50 values of 6.7, 4.3, 2.3, and 6.0 nM, respectively. OTSSP167 inhibited the phosphorylation of PSMA1 and DBNL. OTSSP167 suppressed mammosphere formation of breast cancer cells through the inhibition of PSMA1 phosphorylation.

Animal experiment [1]:

Animal models

Mice bearing MDA-MB-231 xenografts, mice carrying A549 (lung cancer) xenografts

Dosage form

Intravenous administration, 20 mg/kg, once every two days; Oral administration, 10 mg/kg once a day

Application

In mice bearing MDA-MB-231 xenografts, intravenous administration of OTSSP167 at 20 mg/kg once every two days resulted in tumor growth inhibition (TGI) of 73%. Oral administration at 10 mg/kg once a day revealed TGI of 72%. In mice carrying A549 (lung cancer) xenografts, treatment with 1, 5, and 10 mg/kg once a day of OTSSP167 by intravenous administration revealed TGI of 51, 91, and 108%, respectively and those by oral administration of 5 and 10 mg/kg once a day revealed TGI of 95 and 124%, respectively. In DU145 (prostate cancer) and MIAPaCa-2 (pancreatic cancer) xenograft models, oral administration of 10 mg/kg once a day resulted in TGI of 106 and 87%, respectively.

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.

产品描述

OTSSP167 is an inhibitor of maternal embryonic leucine zipper kinase (MELK) with IC50 value of 0.41nM [1].

MELK is a member of the AMPK serine/threonine kinase family and is involved in the mammalian embryonic development. It plays roles in cancer cell growth and formation or maintenance of cancer stem cells. OTSSP167 is a small-molecule inhibitor and can inhibit MELK’s activity effectively and selectively. OTSSP167 inhibits cell proliferation of a variety of cancer cell lines including A549, T47D, DU4475 and 22Rv1. The IC50 values are 6.7nM, 4.3nM, 2.3nM and 6nM, respectively. In mice bearing MDA-MB-231 xenograft, administration of OTSSP167 inhibits 70% tumor growth at dose of 20 mg/kg. Besides that, OTSSP167 is also found to have effects on PSMA1 and DBNL which are the novel substrates of MELK. It inhibits the phosphorylation of PSMA1 and DBNL causes the subsequent suppression of mammosphere formation [1].
