シールエンハンサーを使用しないCRACチャネルアッセイ(ポスター)

カルシウム放出活性化チャネル(CRAC)は、自己免疫疾患、転移性乳癌、糖尿病、炎症性腸疾患などで重要な役割を果たすとともに、移植拒絶反応を予防する可能性があることが知られています。そのため、CRACチャネル電流(ICRAC)の活性を調節する分子が注目されています。

フッ化物は、CRACチャンネルを研究するアッセイでは禁物です。良好な高膜抵抗値(ギガオームシール)を達成するために、一部のオートッパチクランプメーカーはフッ化物などのシール増強剤に大きく依存しています。そのため、自動パッチクランプ装置でCRACチャネルのアッセイを行うことは困難とされてきました。しかしSophionの装置では、フッ化物を使用しない、真のギガシールの形成を保証します。

レビュー論文: 医薬品開発における高齢者向けの安全性薬理学上の課題

高齢者人口の増加が創薬に与える問題は深刻であるにもかかわらず、高齢者のための医薬品開発に対する具体的な解決策は限られています。このことは、世界中を巻き込んだ問題になる恐れがあります。

元ファイザー社の安全性薬理学の専門家であるBernard Fermini氏と弊社のDamian Bellは、創薬コミュニティに対して、高齢者層向けの医薬品の適切かつ堅牢で安全性試験を開発・実施するための議論を開始し行動するよう、その示唆に富むレビューの中で呼びかけています。

私たちは、このレビュー論文をオープンアクセスとしましたので、ぜひご一読ください。

Sophion – 創薬におけるイノベーションの促進

QPatchデータを利用した特許が世界中で公開されるケースが増えています。2005年以降、QPatchによる高品質な電気生理学データのサポートを受けた350件以上の特許ファミリーが公開されています。昨年だけでも60件の特許ファミリーがQPatchデータのサポートを受けて公開されており、年間の特許出願件数は増加傾向にあります。

特許の大部分は米国(46%)で登録されており、これに日本、英国(各11%)、スイス(10%)が追随しています。残りの22%は様々な国からの登録で、中国がそのうちの5%を占め、ドイツ、イタリア、デンマーク、スウェーデンなどが続いています。
特許出願の大半が、塩野義製薬、大日本製薬住友製薬、ノバルティス、アストラゼネカ、Johnson&Johnson、ギリアドなどの大企業からのものであることにさほど驚きはありませんが、小規模な製薬会社の多くが自身の特許出願の一部にQPatchデータを利用していることは驚くべきことです。


QPatchのデータが創薬、化合物の特性評価、心臓安全性試験だけでなく、特許出願でも世界中で積極的に活用されていることを嬉しく思います。

Sophion user meeting in our new facilities in Japan

To accommodate the needs of a growing customer base in Japan, we have expanded our laboratory and demo space in our Japanese facilities in Honjo-Waseda. This was celebrated with a three day user meeting; two days with work shop and one day with seminar with great talks on science. Both the demo room with QPatch and Qube side by side as well as the conference room were in use to accommodate the approx. 30 users that wanted to learn about the latest tips, tricks and software for QPatch and Qube 384. A great success with active interaction and continuing into the evenings with delicious Japanese foods.

Tecan publishing article about QPatch

We are proud to share with you an article published in Tecans latest journal about Sophion and our work with the QPatch. You can read the article here.

Qube version “Duck” is now available

Enjoy current clamp combined with voltage clamp in the same sweep and on all 384 sites to make you results very tight. Cool or heat at the recording site to investigate the temperature sensitivity of the pharmacology you are interested in. Load Qube with stock solutions and let it dilute it to the final test concentration only seconds before adding it to the cell. This and many more updates is the latest results of the constant development Sophion is putting into our products based on inputs from our customers.

Sophion Bioscience is acquired by Sophion CEO, management and investors

Sophion Bioscience has been acquired by Sophion CEO Thais T. Johansen, its management and a group of experienced investors.

Sophion was founded in 2000 as a spinoff from Neurosearch and have since the beginning been pioneering ion channel research and drug discovery. In 2004 Sophion launched the QPatch automated patch clamp solution, which still today is benchmark for advanced electrophysiology and cardiac safety in drug discovery. In 2013 Sophion Qube was launched taking automated patch clamp to the HTS space and taking automated patch clamping to a whole new level of usability. In between Sophion has continuously improved performance and capabilities and launched pioneering new features such as automated Rs compensation, automated current clamp, integrated cell preparation, etc.

Sophion was in 2011 acquired by Biolin Scientific Holding AB, a company owned by Swedish private equity firm Ratos AB.

Sophion CEO Thais Johansen states “Our new ownership structure and financial partners bring a long-term orientation and expertise in building a high-growth life science business. With this involvement, we are well-positioned to continue investing in innovation, technologies and people”.

Thais also said, “we will continue to build on the Sophion legacy with focus on quality, innovation and customer satisfaction” and continues “I am looking forward to talk to our partners over the next weeks to discuss these changes as well as discuss the many great news we have in pipeline”.

Sophion Bioscience employs approximately 60 people worldwide. It is headquartered in Copenhagen, Denmark and has subsidiaries in Boston, Tokyo and Shanghai, as well as distributors in Japan, India and Korea. Sophion has an install base of 100+ automated patch clamp systems and presence in more than 75% of the TOP20 largest Pharma companies in the world.

Internal solution exchange on Qube 384 – New application report

Internal addition of compounds targeting the chloride channel CIC-1.

We demonstrate a robust ClC-1 assay on Qube with internal addition of compounds. The assay shows biophysical characteristics as expected for ClC-1 with good pharmacology and high Z-score. We further introduce Sophion`s Analyzer software that allows rapid analysis of large data sets to answer advanced electrophysiological questions, in the present case: What is the mode of action of a novel, unknown compound?

Poster presentation (Poster #022)
Temperature effect on hERG channel pharmacology measured by using the Qube automated patch clamp system.

Abstract:

The human ether-à-go-go related gene (hERG) function is important for cardiac repolarization and inhibition of the channel can prolong the cardiac action potential, which give increased risk for ventricular arrhythmias including torsade des points (TdP). Therefore, In vitro evaluations of the compound effects is performed on the hERG channel routinely in drug development projects to detect potential arrhythmic side-effects.

Usually these compound measurements are carried out at ambient temperatures. Previously it has been shown that the potency for many compounds have been underestimated when compared to near physiological temperature tests. Therefore, a temperature controlled measuring environment is beneficial when testing compounds for the aims as mentioned here.

Until recently, the only possibility to test compound potency under voltage control conditions has been the manual patch clamp technique. Now automated patch clamp instruments with temperature control have come available making it possible to perform up to 384 parallel recordings at controlled temperatures ranging from 18°C and above.

Here we used an automated patch clamp system, Qube, to study the effect of temperature on concentration response relationships on a panel of compounds known to block the hERG channel. Qube has a temperature controlled test environment and in these studies, we show that temperature merits being taken into consideration when evaluating for hERG potency.
