Currently, around 40 million people worldwide are living with human immunodeficiency virus (HIV) infection making HIV a critical global health risk. Present therapies for HIV infection consist of drug cocktails that target different steps of the HIV life cycle to prevent infection, replication, and release of the virus. Due to its mutating nature, drug resistance coupled with side-effects of long-term drug use, novel strategies, and pharmaceuticals to treat and manage HIV infection are constant needs and continuously being studied. Plants allocate a major repertoire of chemical diversity and are therefore regarded as an important source of new bioactive agents that can be utilized against HIV. Since the early 1990s, upon recommendations of the World Health Organization, numerous studies reported phytochemicals from different structural classes such as flavonoids, coumarins, tannins and terpenes with strong inhibitory effects against HIV infection. The present review gathered and presented recent research (2021-present) on plant extracts and phytochemicals that exhibit anti-HIV properties with the aim of providing insights into future studies where ethnomedical and underutilized plant sources may yield important natural products against HIV. Considering the relation and importance of HIV treatment with current viral infection risks such as SARS-CoV-2, screening plants for anti-HIV agents is an important step towards the discovery of novel antivirals.

Halophytes have been reported to possess a variety of physiological activities, such as anti-cancer, anti-oxidant, anti-diabetes, anti-inflammatory, and anti-obesity. Studies on the roots of the halophyte Rosa rugosa, in particular, have shown a variety of physiological activities and are known to be effective for nursing diabetic complications in traditional Korean medicine. In this study, the effect of R. rugosa on adipogenesis was investigated in 3T3-L1 pre-adipocytes treated with crude extract and solvent fractions (H₂O, n-BuOH, 85% aq. MeOH, and n-Hex) obtained from R. rugosa roots. Treatment with extract and the solvent fractions inhibited the formation of intracellular lipid droplets in differentiated 3T3-L1 adipocytes compared to the untreated group. In particular, n-BuOH and 85% aq. MeOH fractions effectively decreased the expression of adipogenic transcription factors: peroxisome proliferator activated receptor-γ (PPARγ), CCAAT/enhancer-binding protein α (C/EBPα), and sterol regulatory element-binding protein 1c (SREBP1c) in both mRNA and protein levels. In conclusion, these results suggest that R. rugosa contains anti-adipogenic molecules that can be utilized as a nutraceutical against obesity. Further refining of n-BuOH and 85% aq. MeOH fractions and analysis of their action mechanisms could yield potential therapeutic agents with anti-adipogenic effects.

In this study, we investigated in vitro anti-obesity activity of Parthenocissus tricuspidata (Siebold & Zucc.) Planch stem (PTS) in mouse adipocytes 3T3-L1 cells. PTS inhibited lipid accumulation and reduced the expression level of the proteins such as C/EBPα, PPARγ and FABP4 associated with adipogenesis in 3T3-L1 cells. In addition, PTS increased lipolysis-related protein expression such as p-AMPK, ATGL and p-HSL, and reduced perilipin-1 in 3T3-L1 cells. Taken together, PTS may have anti-obesity activity through inhibiting adipogenesis and inducing lipid lipolysis in adipocytes. Based on these results, PTS is expected to be used as a potential functional agent for anti-obesity.

Hericium erinaceus, an edible and medicinal mushroom belonging to the Basidiomycota family, has been used for curing gastric ulcers and stomach cancers in human beings and is also known to have good inhibitory effects on sarcoma 180 and Ehrlich carcinoma in mice. Neutral saline soluble (0.9% NaCl), hot water soluble and methanol soluble substances (hereinafter referred to as Fr. NaCl, Fr. HW and Fr. MeOH, respectively) were extracted from the fruiting body of the mushroom. In in vitro cytotoxicity tests, crude polysaccharides were not cytotoxic against cell lines such as Sarcoma 180, HepG2, HT-29 and NIH3T3 at concentrations of $10{\sim}2,000\;{\mu}g/ml$. Intraperitoneal injection with crude polysaccharides exhibited a life prolongation effect of 29.1~54.1% in mice previously inoculated with Sarcoma 180. Fr. Na increased the numbers of spleen cells by 2.9 fold at a concentration of $50\;{\mu}g/ml$ compared with the control. Fr. Na improved the immuno-potentiating activity of B lymphocytes by increasing alkaline phosphatase activity by 5.5 fold compared with the control at a concentration of $200\;{\mu}g/ml$. Fr. NaCl increased the numbers of peritoneal exudate cells and circulating leukocytes by 4 and 2.3 folds at a concentration of 50 mg/kg, respectively. Therefore, the crude polysaccharides extracted from the fruiting body of H. erinaceus could improve antitumor activities in mice.

Obesity, the world's leading metabolic disease, is a serious health problem in both industrialized and developing countries. Natural substances are of great interest in preventative medicine, especially in the field of metabolic syndromes-from insulin resistance to obesity and diabetes. In the present study, we investigated the effect of A. pullulans SM-2001 Extract (Polycan^®) on the adipocyte differentiation of 3T3-L1 preadipocytes and the anti-obesity effect of 3T3-L1 adipocytes. Although β-glucan has been found to have health benefits in the regulation of the immune system and blood cholesterol levels, its role in obesity has not been fully investigated. Polycan^® suppressed lipid accumulation and glycerol-3-phosphate dehydrogenase (GPDH) activity without affecting cell viability in 3T3-L1 preadipocytes and adipocytes. Polycan^® also inhibited cellular lipid accumulation through down-regulation of transcription factors, such as PPARγ and C/EBPα, and induced dose-dependent phosphorylation of AMP-activated protein kinase (AMPK)-a cellular energy sensor-while the total AMPK protein content remained unchanged. Taken together, this shows that the activation of AMPK by Polycan^® in adipocytes plays a critical role in Polycan^®-induced inhibition of adipocyte differentiation. Our results show that Polycan^® has an anti-obesity action in vitro, suggesting a potential novel preventative agent for obesity and other metabolic diseases.

Natural products have always been an attractive source in terms of novel anti-metastatic compounds which can hinder MMP expression and activity. Corydalis heterocarpa is a salt marsh plant found in the seashores throughout Korea. Its yellow flowers and spikes have been an ingredient in folk medicine to treat spasm and contractions. The present study assessed the potential of different solvent-based fractions from the crude extract of Corydalis heterocarpa (CHE), a halophyte with reported bioactivities, to suppress the PMA-induced MMP expression in human fibrosarcoma HT-1080 cells. The solvent fractions which were named after the solvent used for fractionation (n-hexane, 85% aqueous (aq.) methanol (MeOH), n-butanol (BuOH), and H₂O were shown to inhibit the both elevated mRNA and protein expression levels of MMP-2 and MMP-9 and simultaneously relieved the suppression on the expression of the endogenous MMP inhibitors TIMP-1 and TIMP-2. Results indicated that the CHE fractions might intervene with the PMA-induced activation of the MAPK signaling which is the upstream activator of MMP overexpression. Among tested samples, 85% aq. MeOH and n-hexane fractions of CHE was determined to be the most active and future studies to isolate the bioactive substances responsible for the regulation of the MMP expression are, therefore, urged. In conclusion, C. heterocarpa was shown to be a potential source of anti-metastatic compounds and n-Hexane and MeOH fractions might yield lead molecules to develop novel MMP inhibitors.
