Introduction of Drug Screen

hitstructure.com (Topscience Co., Ltd) is a specialized platform providing services for drug development. Focused on the field of new drug research and development, we offer three major categories of services closely related to drug development for scientists: compound procurement, compound services, and technical services. We have established good partnerships with over ten professional suppliers of medicinal chemicals worldwide, cataloging more than 13 million screening compounds and building blocks available for supply.

We also have an excellent professional team engaged in high-throughput screening, computer-aided virtual screening, activity research, and animal experiments. Our goal is to overcome some obstacles in the drug development process, create a one-stop shop for drug screening, and provide scientists worldwide with convenient, transparent services for chemical transactions and product services in medicinal chemistry, as well as reliable and professional preclinical drug development services.

Convenient Compound Inquiry and Procurement Platform

For scientists, compound procurement is a tedious and time-consuming task. We aim to help global drug development scientists break free from the intricacies of compound procurement, allowing them more time to focus on their research. Compound procurement, as a specific task, requires specialized knowledge and software. DrugScreenNet has professional capabilities and extensive experience in compound procurement and is eager to be your dedicated procurement department.

hitstructure.com has compiled product catalogs from major suppliers of medicinal chemicals and established corresponding commercial compound databases to meet the needs of compound product queries. Based on this data, we have created a chemical ordering platform. At DrugScreenNet, you can use advanced structure search methods to find specific compounds or conveniently purchase large quantities of compounds through batch search functionality. Once the desired compounds for purchase are confirmed, you can place orders through DrugScreenNet's online store or send your order requirements via email. Before finalizing the order, we will provide detailed information on the ordered products, including selected items, corresponding prices, shipping costs, handling fees, and estimated delivery times. Additionally, you can track the progress of each order in your personal account to stay informed about the purchase process.

Full Range of Drug Discovery Laboratories

Every scientist has his or her own area of expertise, but drug discovery is a long, costly and high-risk process involving many fields. Scientists in the field of biology rarely study drug synthesis, and scientists in the field of drug synthesis often need to spend a lot of time and energy to study the mechanism of drug action. Drug Screen has a professional drug research and development laboratory and experimental team, the use of years of accumulated expert resources with the world's well-known universities and research institutes to establish a close cooperation with the top scholars.
Drug screens can provide you with computer virtual screening, target-based drug activity screening, and anti-tumor screening.

In vitro screening of drugs as well as animal experiments and compound library customization and other drug development services. We have more than 600 target screening models, including tyrosine kinases, demethylated histones and other common targets. We also have a library of more than 140 STR-identified human tumor cells and multiple animal models to accelerate your drug development. You only need to put forward specific requirements, we will evaluate the feasibility of the experiment according to your needs, and arrange the corresponding screening and testing services, and will provide you with a professional test analysis report after the completion of the experiment.
