Abstract:
One third of the world’s population is infected with Mycobacterium tuberculosis, causing two million deaths annually. The bacteria avoid immune clearance by persisting within macrophages by subverting normal phagosome maturation and acidification. In order to spread, the bacteria induce necrotic death of its host macrophage, broadcasting the infection into neighboring cells. However, it has long been appreciated that the apoptotic, rather than necrotic death of an infected macrophage results in bacterial growth suppression, improved adaptive immune response and survival.

Abstract:
The global emergence of drug resistance is posing increasing difficulties in the public health control and treatment of tuberculosis (TB). Fluoroquinolones (FQs) are regarded as having a pivotal role among the antimicrobial agents in multidrug regimens against multidrug-resistant tuberculosis (MDR-TB). Thus, early diagnosis of fluoroquinolone-resistant (FQr) MDR-TB and extensively drug-resistant tuberculosis (XDR-TB) by molecular tests has predictive value for the guidance of TB therapy. The pharmacokinetic (PK) and pharmacodynamic (PD) indices are valuable parameters to evaluate the

碩士<br>國立交通大學<br>應用化學系碩博士班<br>105<br>This thesis has two parts: The first part is about synthesis of benzimidazole linked indoline derivatives from C-2-linked-o-aminobenzyl benzimidazole by acid catalyst. This method can apply to various funtional groups. There is no published paper refer to benzimidazole linked indoline derivatives, so we hope these heterobicyclic molecules can show more bioactivity and also hope this thesis can open a new page for research of drugs. The second part is about One-pot synthesis of derivative of ellipticine which has the activity against Mycobacterium tuberculosi

Abstract:
β-lactamase enzymes catalyze the irreversible hydrolysis of the four-membered cyclic amide ring characteristic of β-lactam antibiotics rendering them inactive and useless against pathogenic bacteria. Understanding structure activity relationships between β-lactam antibiotics and β-lactamases is important for designing novel β-lactams, β-lactamase inhibitors, and β-lactam-based fluorescent probes for rapid diagnosis of β-lactam antibiotic resistant infections. The first half of this study focuses on the class A β-lactamase BlaC from Mycobacterium tuberculosis (Mtb) and addresses intermolecula

Although numerous pharmacological effects of trans-CA, such as anti-inflammation, anti-oxidation, and anti-cancer, have been found, cis-cinnamic acid (cis-CA) is considered possesses a higher physiological activity than trans-CA.

Matrix metalloproteinases (MMPs) are key enzymes in the degradation of extracellular matrix, and MMP-2 and -9 are critical for cell migration leading to invasion and metastasis of cancer. The inhibition of MMP-2 and -9 is therefore considered that might depress the occurrence of tumor invasion and metastasis. Rosmarinic acid (RA) is a bioactive polyphenol that widely presented in Rosmarinus officinalis L.
