Abstract
Thymus species are well known as medicinal plants because of their biological and pharmacological properties. Thymus migricus Klokov & Desj. -Shos belongs to Lamiaceae. Young branches of this plant produce an essential oil that is abundant in potent and volatile compounds that have a variety of therapeutic uses. In this study, the natural composition of thymol in this plant’s essential oil was first detected with HPLC and Mass, and then the essential oil was extracted. The increase in the lipophilicity of the synthesized silylated derivatives was then examined by HPLC after numerous silylated derivatives of this phenolic compound were synthesized using various silylation reagents. These derivatives were then analyzed by FT-IR and 1HNMR analysis. The antibacterial activity of thymol with its silylated derivatives against gram-negative and gram-positive bacteria was next tested by diffusion method, after which the antioxidant activity of thymol with its silylated derivatives was assessed by two DPPH and FRAP methods.

Abstract
In this work, we synthesized some organosilicon derivatives of piroxicam. Due to some properties of organosilicon compounds, including increased lipophilicity and thermal stabilization and prodrug for drugs, some silyl ethers of this drug were synthesized and characterized. Increasing of the lipophilic properties of this drug can be very important in the rate of absorption and its effectiveness. We synthesized silyl ethers of this drug, in the next step some copolymers this drug was synthesized. All of compounds were identified by spectroscopic methods.
