Abstract
Antimicrobial resistance has been posing an alarming threat to the treatment of infectious diseases over the years. Ineffectiveness of the currently available synthetic and semisynthetic antibiotics has led the researchers to discover new molecules with potent antimicrobial activities. To overcome the emerging antimicrobial resistance, new antimicrobial compounds from natural sources might be appropriate. Secondary metabolites from natural sources could be prospective candidates in the development of new antimicrobial agents with high efficacy and less side effects. Among the natural secondary metabolites, diterpenoids are of crucial importance because of their broad spectrum of antimicrobial activity, which has put it in the center of research interest in recent years. The present work is aimed at reviewing recent literature regarding different classes of natural diterpenes and diterpenoids with significant antibacterial, antifungal, antiviral, and antiprotozoal activities along with their reported structure-activity relationships. This review has been carried out with a focus on relevant literature published in the last 5 years following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A total of 229 diterpenoids from various sources like plants, marine species, and fungi are summarized in this systematic review, including their chemical structures, classification, and significant antimicrobial activities together with their reported mechanism of action and structure-activity relationships. The outcomes herein would provide researchers with new insights to find new credible leads and to work on their synthetic and semisynthetic derivatives to develop new antimicrobial agents.

Plasmodium falciparum purine nucleoside phosphorylase as a model in the search for new inhibitors by high throughput screening. Int J Biol Macromol 2020; 165:1832-1841. [PMID: 33075341 DOI: 10.1016/j.ijbiomac.2020.10.062] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2020] [Revised: 09/28/2020] [Accepted: 10/09/2020] [Indexed: 10/23/2022]
Abstract
Studies have shown that inhibition of Plasmodium falciparum Purine Nucleoside Phosphorylase (PfPNP) blocks the purine salvage pathway in vitro and in vivo. In this study, PfPNP was evaluated as a model in the search for new inhibitors using surface plasmon resonance (SPR). Its expression, purification, oligomeric state, kinetic constants, calorimetric parameters and kinetic mechanisms were obtained. PfPNP was immobilized on a CM5 sensor chip and sensorgrams were produced through binding the enzyme to the substrate MESG and interactions between molecules contained in 10 fractions of natural extracts. The oligomeric state showed that recombinant PfPNP is a hexamer. The true steady-state kinetic parameters for the substrate inosine were: KM 17 μM, kcat 1.2 s-1, VMax 2.2 U/mg and kcat/KM 7 × 10-4; for MESG they were: KM 131 μM, kcat 2.4 s-1, VMax 4.4 U/mg and kcat/KM 1.8 × 10-4. The thermodynamic parameters for the substrate Phosphate were: ΔG - 5.8 cal mol-1, ΔH - 6.5 cal mol-1 and ΔS - 2.25 cal mol-1/degree. The ITC results demonstrated that the binding of phosphate to free PfPNP led to a significant change in heat and association constants and thermodynamic parameters. A sequential ordered mechanism was proposed as the kinetic mechanism. Three plant extracts contained molecules capable of interacting with PfPNP, showing different levels of affinity. The identification of plant extract fractions containing molecules that interact with recombinant PfPNP using SRP validates this target as a model in the search for new inhibitors. In this study, we showed for the first time the true steady-state kinetic parameters for reactions catalyzed by PfPNP and a model using PfPNP as a target for High-throughput Screening for new inhibitors through SPR. This knowledge will allow for the development of more efficient research methods in the search for new drugs against malaria.

Abstract
An extract of Galtonia regalis from the Natural Products Discovery Institute showed moderate antiplasmodial activity, with an IC50 value less than 1.25 μg/mL. The two known cholestane glycosides 1 and 2 and the five new cholestane glycosides galtonosides A-E (3-7) were isolated after bioassay-directed fractionation. The structures of the new compounds were determined by interpretation of their NMR and mass spectra. Among these compounds, galtonoside B (4) displayed the most potent antiplasmodial activity, with an IC50 value of 0.214 μM against the drug-resistant Dd2 strain of Plasmodium falciparum.

Abstract
Eight isovaleryllignans (1-4 and 8-11), three isovalerylphenylpropanoids (5-7), three known lignans (12-14), and four known compounds were isolated from an extract of the aerial part of Brachanthemum gobicum. The structures of the isolated compounds were elucidated based on NMR and MS data analyses. The enantiomers of compounds 1-3, 5, 8, and 9 were isolated using chiral-phase HPLC, and the absolute configurations of 1a/1b-3a/3b, 5a/5b, 8a/8b, and 9a/9b were elucidated from their optical rotations and ECD spectra; the other lignans were assumed to be racemic or scalemic by chiral-phase HPLC analyses and optical rotation data. Some of the acylated lignans (racemic mixtures) (1-4, 8, 9, and 12-14) exhibited moderate inhibitory activities against Trypanosoma congolense, the causative agent of nagana disease in animals.
