Abstract

Lopinavir is an antiretroviral of the protease inhibitor class (Figure 1 and Figure 2). It is used against HIV infections as a fixed-dose combination with another protease inhibitor, ritonavir (lopinavir/ritonavir). In the current research, the stimulated ATR-FTIR biospectroscopy of liquid sample of Lopinavir was investigated. The stimulated ATR-FTIR diffractions emitted through focusing the second harmonic laser beam Nd:YAG into the sample were recorded by Echelle spectrometer and ICCD detector. Increasing the energy of laser beam from 2.6 (mJ) to 16 (mJ) led to increase in stimulated ATR-FTIR signal but after breakdown threshold of liquid sample, further increasing energy led to the decrease in stimulating ATR-FTIR signals and for energies higher than 20 (mJ), they were disappeared.

ATR-FTIR生物光谱法原位表征洛匹那韦
洛匹那韦是一种蛋白酶抑制剂类抗逆转录病毒药物(图1和图2)。它与另一种蛋白酶抑制剂利托那韦(洛匹那韦/利托那韦)固定剂量联合用于治疗HIV感染。本研究对洛匹那韦液体样品的受激ATR-FTIR生物光谱进行了研究。利用Echelle光谱仪和ICCD探测器记录了二次谐波激光束Nd:YAG聚焦样品后发射的受激ATR-FTIR衍射。当激光束能量从2.6 (mJ)增加到16 (mJ)时,受激ATR-FTIR信号增加,但在液体样品击穿阈值之后,进一步增加能量导致受激ATR-FTIR信号减少,当能量高于20 (mJ)时,受激ATR-FTIR信号消失。

期刊介绍: The Journal of Theoretical and Computational Chemistry (JTCC) is an international interdisciplinary journal aimed at providing comprehensive coverage on the latest developments and applications of research in the ever-expanding field of theoretical and computational chemistry. JTCC publishes regular articles and reviews on new methodology, software, web server and database developments. The applications of existing theoretical and computational methods which produce significant new insights into important problems are also welcomed. Papers reporting joint computational and experimental investigations are encouraged. The journal will not consider manuscripts reporting straightforward calculations of the properties of molecules with existing software packages without addressing a significant scientific problem. Areas covered by the journal include molecular dynamics, computer-aided molecular design, modeling effects of mutation on stability and dynamics of macromolecules, quantum mechanics, statistical mechanics and other related topics.
