Nerolidol (3,7,11-trimethyl-1,6,10-dodecatrien-3-ol) is a naturally occurring sesquiterpene alcohol that present in various plants with floral odor. It synthesized as an intermediate the production of (3E)-4,8-dimethy-1,3,7-nonatriene (DMNT), herbivore-induced volatile protects from herbivore damage. Chemically, nerolidol exists two geometric isomers, trans and cis form. The usage widespread across different industries. has been widely used cosmetics (e.g., shampoos perfumes) non-cosmetic products detergents cleansers). In fact, U.S. Food Drug Administration (FDA) also permitted use food flavoring agent. fact common ingredient many attracted researchers to explore more medicinal properties may exert beneficial effect on human health. Therefore, aim this review compile consolidate data pharmacological biological activities displayed by nerolidol.

Medicinal chemists continue to be fascinated by chalcone derivatives because of their simple chemistry, ease hydrogen atom manipulation, straightforward synthesis, and a variety promising biological activities. However, chalcones have still not garnered deserved attention, especially considering high potential as chemical sources for designing developing new effective drugs. In this review, we summarize current methodological developments towards the design synthesis state-of-the-art medicinal chemistry strategies (bioisosterism, molecular hybridization, pro-drug design). We also highlight applicability computer-assisted drug approaches address how may contribute optimizing research outputs lead more successful cost-effective discovery endeavors. Lastly, present examples use suggest possible solutions existing limitations.

Leishmaniasis is a neglected infectious disease caused by several different species of protozoan parasites the genus Leishmania . Current strategies to control this are mainly based on chemotherapy. Despite being available for last 70 years, leishmanial chemotherapy has lack efficiency, since its route administration difficult and it can cause serious side effects, which results in emergence resistant cases. The medical-scientific community facing difficulties overcome these problems with new suitable efficient drugs, as well identification drug targets. availability complete genome sequence given scientific possibility large-scale analysis, may lead better understanding parasite biology consequent novel In review we focus how high-throughput analysis helping us other groups identify targets chemotherapeutic interventions.

It one of the most plants for treatment diabetes worldwide. In previous studies, was shown to possess antihyperlipidemic anti-allergic properties, exhibit good performance an antimicrobial agent bacteria, fungi, protozoa parasites genus Leishmania Trypanosoma. This study aimed at evaluating effects S. essential oil (ScEO) its major component α-pinene on (Leishmania) amazonensis, well their cytotoxicity possible mechanisms action.To evaluate anti-proliferative effect Leishmania, promastigote axenic amastigote forms were assessed using tetrazolium salt (MTT) assay. The intramacrophagic amastigotes exposed ScEO determine survival index.

Abstract Infectious diseases continue to be one of the major contributors human morbidity. The rapid rate at which pathogenic microorganisms have developed resistance against frontline antimicrobials has compelled scientists look for new alternatives. Given their vast antimicrobial repertoire, substantial research effort been dedicated toward development peptides (AMPs) as alternative drugs. However, inherent limitations AMPs driven efforts worldwide develop synthetic mimics AMPs. This review focuses on progress that made small molecules emulate properties AMPs, both in terms design and biological activity. Herein we provide an extensive discussion structural features various designs examine exploited. Furthermore, raise a number questions field yet solutions discuss possible future directions remain either unexploited or underexploited.

Leishmaniasis remains a public health problem worldwide, affecting approximately 12 million people in 88 countries; 50 000 die of it each year. The disease is caused by Leishmania, obligate intracellular vector-borne parasites. In spite its huge impact on the populations vast areas, leishmaniasis one most neglected diseases. No safe and effective vaccine currently exists against any form human leishmaniasis. spectrum efficacy available antileishmanial drugs are also limited. First part this review discusses approaches used for vaccination that based pathogen includes virulent or attenuated parasites, parasites related nonpathogenic species, whole killed parasites' subunits, DNA vaccines, vaccines saliva components transmitting phlebotomine vector. Second describes parasite detection quantification using microscopy assays, cell cultures, immunodetection, DNA-based methods, shows progress development application these techniques. third part, first-line alternative to treat characterized, pre-clinical research range natural synthetic compounds studied leishmanicidal activity described. suggests novel strategies advances genetics, genomics, advanced delivery systems, high throughput screenings would lead improvement prevention treatment disease.
