Abstract
BACKGROUND Antimicrobial resistance development poses a significant danger to the efficacy of antibiotics, which were once believed to be the most efficient method for treating infections caused by bacteria. Antimicrobial resistance typically involves various mechanisms, such as drug inactivation or modification, drug target modification, drug uptake restriction, and drug efflux, resulting in decreased antibiotic concentrations within the cell. Antimicrobial resistance has been associated with efflux Pumps, known for their capacity to expel different antibiotics from the cell non-specifically. This makes EPs fascinating targets for creating drugs to combat antimicrobial resistance (AMR). The varied structures of secondary metabolites (phytomolecules) found in plants have positioned them as a promising reservoir of efflux pump inhibitors. These inhibitors act as modifiers of bacterial resistance and facilitate the reintroduction of antibiotics that have lost clinical effectiveness. Additionally, they may play a role in preventing the emergence of multidrug resistant strains. OBJECTIVE The objective of this review article is to discuss the latest studies on plant-based efflux pump inhibitors such as terpenoids, alkaloids, flavonoids, glycosides, and tetralones. It highlighted their potential in enhancing the effectiveness of antibiotics and combating the development of multidrug resistance. strains. RESULTS Efflux pump inhibitors (EPIs) derived from botanical sources, including compounds like lysergol, chanaoclavine, niazrin, 4-hydroxy-α-tetralone, ursolic acid, phytol, etc., as well as their partially synthesized forms, have shown significant potential as practical therapeutic approaches in addressing antimicrobial resistance caused by efflux pumps. Further, several phyto-molecules and their analogs demonstrated superior potential for reversing drug resistance, surpassing established agents like reserpine, niaziridin, etc. strains. CONCLUSION This review found that while the phyto-molecules and their derivatives did not possess notable antimicrobial activity, their combination with established antibiotics significantly reduced their minimum inhibitory concentration (MIC). Specific molecules, such as chanaoclavine and niaziridin, exhibited noteworthy potential in reversing the effectiveness of drugs, resulting in a reduction of the MIC of tetracycline by up to 16 times against the tested strain of bacteria. These molecules inhibited the efflux pumps responsible for drug resistance and displayed a stronger affinity for membrane proteins. By employing powerful EPIs, these molecules can selectively target and obstruct drug efflux pumps. This targeted approach can significantly augment the strength and efficacy of older antibiotics against various drug resistant bacteria, given that active drug efflux poses a susceptibility for nearly all antibiotics.

Abstract
Malaria the parasitic disease of tropical countries is seeking newer therapeutic strategies owing to the drug resistance to existing drugs. The pathogenesis after infection renders the host to oxidative stress resulting in an altered immune status. Natural products rich in phenols are a source of bio-actives that could have a role in alleviating such condition. The present study reports the phenol rich ethyl acetate extract from the petals of Rosa damascena (RdEa) to be active against Plasmodium falciparum in-vitro and Plasmodium berghei in-vivo. It restores the haemoglobin level while increasing the mean survival time and chemo-suppression in P. berghei infected mice. The HPLC characterised RdEa was found to be rich in Gallic acid and Rutin besides other phenols. RdEa was capable of scavenging the free radicals and modulating the pro-inflammatory mediators (IL6, TNF, IFN and NO) favourably and also restored the architecture of hepatocytes as evidenced through histopathology. The extract was able to arrest the lipopolysaccharide (LPS) induced damage of J774A.1 cells (murine macrophages) and was found to be safe in mice upto 2000 mg/kg body weight.

Abstract
BACKGROUND Lawsonia inermis L. is a well-documented plant for cosmetic as well as medicinal properties. It is used by local communities in India and Nigeria for the treatment of many parasitic diseases, including malaria. HYPOTHESIS/PURPOSE Earlier studies on the plant's antiplasmodial activity were not assigned to any phytochemical with no quality assurance data. In this report, a recent chemically characterized extract and it's major constituent were investigated for in vitro antiplasmodial activity on chloroquine sensitive NF-54 strain. Furtherly, the potent extract and this constituent were assessed in vivo in Plasmodium berghei infected mice. The bioactive phytochemical and enriched extract were also monitored against various oxidative stress parameters. STUDY DESIGN/METHOD The extract characterization was done by the quantitative analysis of eight phytochemicals using gradient reverse phase HPLC method. In vitro antiplasmodial activity was evaluated on chloroquine sensitive NF-54 strain by the determination of pfLDH activity. In vivo activity of the most potent extract and constituent were evaluated in P. berghei infected mice upon oral administration. The estimation of oxidative stress was done by monitoring various enzymatic and non-enzymatic parameters. RESULTS The ethyl acetate extract of leaves (IC50 9.00 ± 0.68 µg/ml) and fraxetin (IC50 19.21 ± 1.04 µM) were the most effective in in vitro assays therefore selected for in vivo tests. The administration of the ethyl acetate extract of leaves and fraxetin to the infected mice resulted in significant (p < .05) suppression of parasitaemia as evidenced by a 70.44 ± 2.58% to 78.77 ± 3.43% reduction compared to non-infected group. In addition, a two-fold increase in mean survival time, a significant (p < .05) reduction in lipid peroxidation and an elevation in glutathione, catalase and superoxide dismutase were also observed in treated mice. The post-infection treatment also led to an augmentation of endogenous antioxidant enzymes (GST, GR, GPx) with respect to the infected control. A significant (p < .05) elevation in serum Nrf2-antioxidant response element level responsible for the activation of endogenous enzymes was also observed. CONCLUSION It was evident from the experiments that ethyl acetate extract of L. inermis and fraxetin were able to suppress the oxidative damage by augmenting endogenous antioxidant system and thus ameliorated the plasmodium infection in mice.

Abstract
Diarylheptanoids from Alnus nepalensis leaves have been reported for promising activity against filariasis, a mosquito-borne disease, and this has prompted us to investigate its anti-malarial and safety profile using in-vitro and in-vivo bioassays. A. nepalensis leaf extracts were tested in-vitro against chloroquine-sensitive Plasmodium falciparum NF54 by measuring the parasite specific lactate dehydrogenase activity. Among all, the chloroform extract (ANC) has shown promising anti-plasmodial activity (IC50 8.06 ± 0.26 µg/mL). HPLC analysis of ANC showed the presence of diarylheptanoids. Efficacy and safety of ANC were further validated in in-vivo system using Plasmodium berghei-induced malaria model and acute oral toxicity in mice. Malaria was induced by intra-peritoneal injection of P. berghei infected red blood cells to the female Balb/c mice. ANC was administered orally at doses of 100 and 300 mg/kg/day following Peter's 4 day suppression test. Oral administration of ANC showed significant reduction of parasitaemia and increase in mean survival time. It also attributed to inhibition of the parasite induced pro-inflammatory cytokines as well as afford to significant increase in the blood glucose and haemoglobin level when compared with vehicle-treated infected mice. In-vivo safety evaluation study revealed that ANC is non-toxic at higher concentration. Copyright © 2016 John Wiley & Sons, Ltd.

Abstract
Conyza sumatrensis (Retz.) E.H. Walker (Cs) leaves are used for traditional treatment of malaria in Cameroon. However, the antimalarial activity of the leaf constituents of this plant is still unexplored. The aim of our investigation was to evaluate the antiplasmodial activity of some bioactive constituents from Cs leaves. Compounds were isolated from Cs leaves and structurally elucidated using extensive spectroscopic analysis. The in vitro antiplasmodial activity of the extracts and pure compounds were evaluated on chloroquine-sensitive strain (NF54) of Plasmodium falciparum. The in vivo assay was done by administering seven doses of extracts in mice infected with Plasmodium berghei K173 through oral route. Cytotoxicity of pure compounds on murine macrophage cells was performed through [3-(4,5-Dimethylthiazol-2-yl)-2,5-Diphenyltetrazolium Bromide] (MTT) test. Hemolysis and lactate dehydrogenase assays were also carried out using standard procedures. The in silico prediction of bioactive constituents was performed through Autodock Vina. Polarity-based extracts from Cs were found to be active against P. falciparum (NF54) and P. berghei (K173) in vitro and in vivo respectively. Further, bioactivity-guided isolation of n-hexane fraction yielded three compounds, (1), (2) and (3) with IC50 of 34, 17.9 and 18μg/ml, respectively, while the ethyl acetate fraction afforded the fourth compound with an IC50 of 25μg/ml, indicating anti-malarial potential of Cs through PfLDH interaction without compromising normal cell growth. This study reports for the first time, the antiplasmodial activity of bioactive constituents from Cs and confirms its traditional use.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Many of the effective therapeutic strategies have been derived from ethnopharmacologically used natural products. Pluchea lanceolata is an herb employed in Indian folk medicine for malaria like fever but it lacks proper pharmacological intervention. AIM OF THE STUDY To evaluate antimalarial and safety profile of Pluchea lanceolata: an in-vitro, in-vivo for its ethnopharmacological validation. MATERIALS AND METHODS Methanol, butanol, ethyl acetate, chloroform, hexane extracts and its isolate, taraxasterol acetate (TxAc) were obtained from air dried aerial part of Pluchea lanceolata. These were tested in-vitro against chloroquine-sensitive strain of Plasmodium falciparum NF54 by measuring the parasite specific lactate dehydrogenase activity. The most potent hexane extract and TxAc were further validated for in-vivo antimalarial and safety evaluation. TxAc, a pentacyclic-triterpene isolated from the most active fraction was further evaluated with special emphasis on inflammatory mediators involved in malaria pathogenesis. Murine malaria was induced by intra-peritoneal injection of Plasmodium berghei infected red blood cells to the male Swiss inbred mice. Mice were orally treated following Peters 4-Day suppression test. In-vivo antimalarial efficacy was examined by evaluating the parasitaemia, percent survival, mean survival time, blood glucose, haemoglobin and pro-inflammatory mediators involved in malaria pathogenesis. RESULTS Hexane extract and TxAc showed promising antimalarial activity in-vitro and in-vivo condition. TxAc attributed in inhibition of the pro-inflammatory cytokines as well as afford to significant increase in the blood glucose and haemoglobin level when compared with vehicle treated infected mice. We have not observed the synergistic action of combinations of chloroquine and TxAc from our experimental results. In-vitro and in-vivo safety evaluation study revealed that hexane extract is non toxic at higher concentration. CONCLUSION Present study further validates the ancient Indian traditional knowledge and use of Pluchea lanceolata as an antimalarial agent. Study confirms the suitability of Pluchea lanceolata as a candidate for further studies to obtain a prototype for antimalarial medicine.
