Innumerable microbial products have been investigated since then, and much work has been done in chemically modifying these natural products in an attempt to enhance the benefits while minimizing the undesirable effects. These modified products, termed semisynthetic antibiotics, increased stability and solubility, improved pharmacokinetics (ie, wider distribution and longer half-life), and increased antimicrobial activity. Minimizing the undesirable effects creates antibiotics with decreased toxicity and increased efficacy.
