Breakthrough: Israeli Scientists Invent Method to Significantly Enhance Drug Efficacy
An innovative method developed by researchers at the Hebrew University and the Weizmann Institute in Israel allows for the elimination of side effects from drugs and makes them more effective. This has been made possible by the results of years of research dedicated to developing a method for separating chiral molecules. The findings of their work were published in one of the most prestigious scientific journals, Science, and they claim to represent a true revolution in the fields of medicine and pharmacology.
Until recently, the term "chirality" was used exclusively in specialized chemical and biological literature. Today, thanks to the active scientific work of Israeli researchers led by Professor Ron Naaman of the Weizmann Institute, chiral molecules have begun to be studied in pharmacology as well. Chirality determines their chemical properties, specifically whether they will "heal or harm." In simple terms, the same molecules that belong to different chiral versions (there are two – right and left) can have both therapeutic and side effects.
Due to the high cost and complexity of purification procedures, chiral purity of active substances in modern medications is extremely rare. Anyone who has ever read the instructions for any medication knows that a list of possible side effects always follows the list of indications. This is a manifestation of chirality. In some cases, it plays a vital role. For example, in the late 1960s, the drug thalidomide was often prescribed to pregnant women to suppress the symptoms of toxemia. It did indeed help, if not for one "but": women who took this drug for an extended period gave birth to children with deformed limbs. Research revealed that this occurred precisely because both the right (D) and left (L) chiral versions were present in the drug's molecules. The former had a therapeutic effect, while the latter led to irreversible developmental defects in the fetus.
The invention by Israeli scientists regarding the separation of chiral versions of molecules has become a true breakthrough in medicine, as until today, such a task was considered unsolvable. Researchers discovered that they behave completely differently on magnetic surfaces. Now, pharmaceutical companies will be able not only to successfully separate D- and L-versions of drugs but also to do so quickly and, importantly, cheaply. This procedure will help minimize side effects and significantly enhance the efficacy of many drugs.
