GORYO Chemical

The company's core business involves the creation of fluorescent probes for cellular analysis, biological assays, and imaging. These products are distributed to a diverse client base that includes academic researchers, biotechnology firms, and large pharmaceutical companies. GORYO Chemical's business model encompasses direct sales of its research reagents and the custom synthesis of fluorescent probes. The company has established a global distribution network through a partnership with Merck KGaA, Darmstadt, Germany, and its affiliate MilliporeSigma in North America, making its products accessible worldwide.

A significant focus of the company is the development of what it terms "navigation drugs." These are activatable fluorescent probes designed for image-guided cancer surgery. By causing cancerous tissues to fluoresce, these agents aim to assist surgeons in the complete removal of malignant cells, a major challenge in oncology. The company is advancing these diagnostic agents through preclinical and clinical trials in Japan. For instance, its breast cancer navigation drug, GCP-006, has had a New Drug Approval (NDA) application filed in Japan. This strategic direction extends to forming partnerships, such as a collaboration agreement with Solasia Pharma Co., Ltd. to jointly commercialize its pharmaceutical business.

The product portfolio is extensive, featuring various series of probes each tailored for specific biological targets and applications. The AcidiFluor™ series detects acidic environments like lysosomes, while the MetalloFluor™ series is designed for detecting metal ions. Other product lines include probes for calcium ions (CalFluor™), glycosidase activity (GlycoFluor™), and human iPS/ES cells (StemFluor™). A notable product is the POLARIC™ probe, a solvatochromic probe that changes its fluorescent color based on the polarity of its micro-environment, allowing it to simultaneously stain different cellular organelles in distinct colors. The company has also developed probes for super-resolution microscopy, such as the HMSIR series, which enables advanced cellular imaging under physiological conditions.
