Sepbox

Nature has a practically infinite variety of useful compounds.....

Throughout history, valuable therapeutic ingredients have always been derived from plants. One well-known example is the willow tree, whose bark was used by the famous greek physician Hippocrates to treat inflammatory diseases around 400 B.C. The effective natural ingredient extracted from this bark has been developed by scientists to make acetylic acid, which forms the basis of many current pain relievers. Today, we use a substance extracted from a nut tree in the Philippines to treat epilepsy. And Curare, a neurotoxic substance derived from lianas vines in the Amazon jungle, is used to relax muscles and treat tetanus.

Natural compounds still play an increasingly important role in many areas of research and development. Their structural diversity is enhanced by the synthetic potential of combinatorial chemistry. There are many new classes of substances waiting to be discovered, and the diversity of these compounds and their chiral
properties means that some of these are certain to be highly marketable. Pharmaceutical research is only just beginning to exploit this diversity.

... unfortunately, they are never found in their pure state

Access to nature’s inexhaustible supply of compounds has increased over recent years. However, unfortunately there isn’t the same limitless supply of ways to process them automatically. Fractionation
and separation of samples obtained from nature remain time-consuming, tedious and extremely expensive, even though the assays for testing these samples have become faster and more cost-effective thanks to advanced high-throughput screening processes. Today, high performance Liquid Chromatography (HPLC) is the standard technology used for separating compounds from natural resources.

Isolate Conventionally

That’s why we need state-of-the art solutions...

Processing natural product extracts represents a major bottleneck that is constricting the pace of drug discovery. To ensure that sample preparation is both reproducible and reliable, it would therefore be of immense benefit to have an automated process in place for natural compound purification. the economic potential of this
is tremendous.

...like Sepbox systems

Sepiatec’s unique Sepbox systems allow samples to be processed automatically, and significantly accelerate the purification process. Results which usually take weeks or months with conventional methods can be obtained in just a few days – or even one day – with a Sepbox system.

The Sepbox concept is based on a patented combination of high performance Liquid Chromatography (HPLC) and solid phase extraction (SPE) – reliable and proven techniques that provide a universal platform suitable for processing large sample numbers. Up to 600 fractions with a very high yield of pure compounds can be efficiently obtained from subsequent high throughput screening. Using two-dimensional separation, the recovery rate for both polar and non-polar substances is usually above 90 per cent. Using an automated and highly reproducible process, one extract can be completely separated per day. The pure individual components are soluted in suitable solvents and can be collected in microtiter plates or vials.

Sepbox 2D-250

Sepbox 250

Extensive lab facilities are no longer essential to separate a large number of novel compounds.
With a Sepbox system, up to 600 fractions can be produced per day, many of them containing pure compounds, without investing large amounts in human resources or research facilities. This saves time and money and significantly accelerates the early stages of the product development process.

The automated Sepbox 2d-250 and 2d-5000 systems allow extracts from plants, marine organisms, microbiological or animal materials to be processed in quantities of up to 250 or 5,000 milligrams respectively. If required, highly polar substances can be separated using the polar setup. The systems are equipped with
two detectors: UV detection (ultraviolet) and optional ELSD detection (evaporative light scattering detection), which can detect almost all substances.

The Sepbox 2D-250 benchtop model is designed for the automated two-dimensional separation of up to 250 milligrams of extracts. Tithe system offers the choice between liquid and adsorbed (solid) sample injection. Up to 600 fractions can be collected in microtiter plates in just 24 hours. Depending on the extract, up to 30 per cent of all fractions usually contain pure compounds.

The Sepbox 250 is suitable for medium to non-polar compounds (polar setup optional).

The system is equipped with intuitive, user-friendly software for method development, process control, data acquisition and data analysis.

Sepbox 2D-5000

Sepbox 2D technology has even more to offer. The Sepbox 2D-5000 is designed for a larger workload of up to 5,000 milligrams of extract from natural sources. The automated 2D chromatography provides up to 576 fractions in 24 hours. The FractionCollector is equipped with six removable racks, each containing 96 vials with a maximum capacity of 45 milliliters.

The Sepbox 2D-5000 is also equipped with software for method development, process control, data acquisition and data analysis. On average, up to 30 per cent of all fractions contain pure compounds
depending on the extract. the fractions are almost free of water and buffer from the second SPE step and can be processed immediately. Optional polar setup is available for polar substances.

The Sepbox 2D-5000 system provides many individual chemical entities in quantums which can be easily used to elucidate structures, screen different targets and build a diverse library.
