The money raised will be used to build a global sales and marketing organization and to invest in further development of the technology, including the development of a larger-scale synthesis system. The company was formed in 1997 as Labwell AB, and has raised $14 million in two previous funding rounds. "With genomics there are a lot more targets out there the bottleneck is lead optimization." Johansson claims that lead optimization times can be cut from two to four years to half that time. Yields are improved because a greater portion of the reactants actually reacts with one another, making the subsequent purification processes faster and easier. With Coherent Synthesis, the seven-minute reaction gives a 93 percent yield With the existing method the process takes 240 hours and produces a 13 percent yield. The reaction in question is the synthesis of aminolyse. In one case the reaction time is cut from 10 days to seven minutes using our equipment." "They can do things they could not do before, and can afford to think creatively because it is easy to test different reactions. "This technology really changes the way medicinal chemists work," Johansson said. Promising compounds may be rejected during lead optimization because synthesis reactions are too difficult, take too long, or do not yield enough of the compound. It comes with ready-to-use reaction mixtures and a reactions database.
The system, called Coherent Synthesis, accelerates chemical reactions up to 1,000 times.
Johansson said there would be no impact on the commercial development of the company, which has developed a laboratory bench system for rapid chemical synthesis using microwaves. We did consider reactivation but the board decided a private placement would be better." "This was not to do with the state of the market. One law firm said there was no problem, another wanted more time. CEO Hans Johansson told BioWorld International, "There was a misunderstanding on a patent, and a question of whether it infringed a U.S. The company, based in Uppsala, Sweden, was to have made its debut on June 22, but pulled out four days earlier. LONDON - Personal Chemistry AB is close to completing a US$20 million private financing, after being forced to pull a $50 million listing on the Stockholm Exchange due to a misunderstanding over patents.
