Inflammation is an initial response of the body to a harmful stimuli and it is achieved by the increased movement of leukocytes (especially granulocytes) from blood into injured tissues. It is required for healing wounds and infections. Despite their indispensable role in microbial killing, the inflammation reactions may also cause diseases to a host such as hay fever, atherosclerosis, and rheumatoid arthritis. The enzymes and oxidizing species released during the inflammatory process can cause damages to the host tissues which lead to inflammatory syndromes. The role of myeloperoxidase (MPO) in the inflammatory reactions is well documented. It contributes in killing the pathogens but it is also implicated in several inflammatory syndromes such as Parkinson's disease, Alzheimer's disease and atherosclerosis. Thus, this enzyme has attracted more attention of the scientists and it has become a target for drug designing. In the last decade, several reversible and irreversible MPO inhibitors were identified as very high potent inhibitors such as fluoroalkylindole, aromatic hydroxamic acid, thioxanthine and benzoic acid hydrazide derivatives. In this review, we tried to illustrate the MPO inhibitors and highlight their structure activity relationship (SAR). In this paper we also discussed the mechanism of the inhibitory effect of the most potent compounds.

In order to systematically describe the Parkinson's disease phenome, we performed a series of 832 cross-sectional case-control analyses in a large database. Responses to 832 online survey-based phenotypes including diseases, medications, and environmental exposures were analyzed in 23andMe research participants. For each phenotype, survey respondents were used to construct a cohort of Parkinson's disease cases and age-matched and sex-matched controls, and an association test was performed using logistic regression. Cohorts included a median of 3899 Parkinson's disease cases and 49,808 controls, all of European ancestry. Highly correlated phenotypes were removed and the novelty of each significant association was systematically assessed (assigned to one of four categories: known, likely, unclear, or novel). Parkinson's disease diagnosis was associated with 122 phenotypes. We replicated 27 known associations and found 23 associations with a strong a priori link to a known association. We discovered 42 associations that have not previously been reported. Migraine, obsessive-compulsive disorder, and seasonal allergies were associated with Parkinson's disease and tend to occur decades before the typical age of diagnosis for Parkinson's disease. The phenotypes that currently comprise the Parkinson's disease phenome have mostly been explored in relatively small purpose-built studies. Using a single large dataset, we have successfully reproduced many of these established associations and have extended the Parkinson's disease phenome by discovering novel associations. Our work paves the way for studies of these associated phenotypes that explore shared molecular mechanisms with Parkinson's disease, infer causal relationships, and improve our ability to identify individuals at high-risk of Parkinson's disease.
