Diabetes mellitus is a life-threatening disorder affecting people of all ages and adversely disrupts their daily functions. Despite the availability of numerous synthetic-antidiabetic medications and insulin, the demand for the development of novel antidiabetic medications is increasing due to the adverse effects and growth of resistance to commercial drugs in the long-term usage. Hence, antidiabetic phytochemicals isolated from fruit plants can be a very nifty option to develop life-saving novel antidiabetic therapeutics, employing several pathways and MoAs (mechanism of actions). This review focuses on the antidiabetic potential of commonly available Bangladeshi fruits and other plant parts, such as seeds, fruit peals, leaves, and roots, along with isolated phytochemicals from these phytosources based on lab findings and mechanism of actions. Several fruits, such as orange, lemon, amla, tamarind, and others, can produce remarkable antidiabetic actions and can be dietary alternatives to antidiabetic therapies. Besides, isolated phytochemicals from these plants, such as swertisin, quercetin, rutin, naringenin, and other prospective phytochemicals, also demonstrated their candidacy for further exploration to be established as antidiabetic leads. Thus, it can be considered that fruits are one of the most valuable gifts of plants packed with a wide spectrum of bioactive phytochemicals and are widely consumed as dietary items and medicinal therapies in different civilizations and cultures. This review will provide a better understanding of diabetes management by consuming fruits and other plant parts as well as deliver innovative hints for the researchers to develop novel drugs from these plant parts and/or their phytochemicals.

Tetrastigma leucostaphylum (Family: Vitaceae) is popular for its medicinal value in Bangladeshi tribal communities. This study aims to investigate several pharmacological values of methanol extract of T. leucostaphylum (METL). In vivo analgesic and anti-inflammatory researches have been implemented by using acetic acid-induced writhing and formalin-induced paw licking test protocols in mice. Furthermore, in vitro thrombolytic and anthelmintic studies have been performed by following the blood clot lysis method and nematode mortality measurement method. In the in vivo study, METL did not minimize the acetic acid-induced writhes prominently but significantly attenuate both the peripheral and inflammatory pain in mice in a dose-dependent manner. In early and late phase, METL 400 (mg/kg, b.w; p.o) showed 39.63 % and 48.73 % paw licking inhibition. Again, METL (100 μL) reflected 56.62 % clot lysis in thrombolytic research. Besides, METL causes the death of nematodes in a dose-dependent manner. The bioassay of the methanol extract of T. leucostaphylum justified the analgesic, anti-inflammatory, thrombolytic and anthelmintic activities of the crude extract and finally suggests the test extract as a wellspring of anti-inflammatory, thrombolytic and anthelmintic agents as a crude drug source.

Bauhinia scandens L. (Family, Fabaceae) is a medicinal plant used for conventional and societal medication in Ayurveda. The present study has been conducted to screen the chemical, pharmacological and biochemical potentiality of the methanol extracts of B. scandens stems (MEBS) along with its related fractions including carbon tetrachloride (CTBS), di-chloromethane (DMBS) and n-butanol (BTBS). UPLC-QTOF–MS has been implemented to analyze the chemical compounds of the methanol extracts of Bauhinia scandens stems. Additionally, antinociceptive and anti-inflammatory effects were performed by following the acetic acid-induced writhing test and formalin-mediated paw licking test in the mice model. The antipyretic investigation was performed by Brewer Yeast induced pyrexia method. The clot lysis method was implemented to screen the thrombolytic activity in human serum. Besides, the in silico study was performed for the five selected chemical compounds of Bauhinia scandens, found by UPLC-QTOF–MS By using Discover Studio 2020, UCSF Chimera, PyRx autodock vina and online tools. The MEBS and its fractions exhibited remarkable inhibition in dose dependant manner in the antinociceptive and antiinflammatory investigations. The antipyretic results of MEBS and DMBS were close to the standard drug indomethacin. Investigation of the thrombolytic effect of MEBS, CTBS, DMBS, and BTBS revealed notable clot-lytic potentials. Besides, the phenolic compounds of the plant extracts revealed strong binding affinity to the COX-1, COX-2, mPGES-1 and plasminogen activator enzymes. To recapitulate, based on the research work, Bauhinia scandens L. stem and its phytochemicals can be considered as prospective wellsprings for novel drug development and discovery by future researchers.
Prospective Asian Plants with Corroborated Antiviral Potentials
(Scopus, 22-04-05) Ashraf, Sania; Rahman, Mamunur; Ahmed, Pollob; Alam, Safaet; Hossain, Md. Abid
Viral diseases are extremely widespread infections caused by viruses. Amongst numerous other illnesses, viral infections have challenged human existence severely. Over the history of mankind, new viruses have emerged and presented us with new tests. The range of viral infections varies from familiar infectious diseases such as the common cold, fu, and warts to severe ailments such as AIDS, Ebola, and COVID-19. The world has been racing to fnd an efective cure for the newly evolving viruses. Toxic efects, non-selectivity, drug resistance, and high price are the most common complications of conventional treatment procedures. Nature is a marvelous source of phytoconstituents with incredible varieties of biological activities. By tradition, medicinal plants have been utilized for the treatment of countless infectious diseases worldwide, some of which contain a broad spectrum of activities. Modern drug discovery and development techniques ofer highly efcient separation techniques, inauguration of vector-based schemes where the original infectious virus is cloned to the non-infectious one for antiviral screening targets. The objective of the review was to gather available data on 20 both cultivated and native plants of Asia giving antiviral activities and provide comprehensive information on the phytochemical analysis of the plants and potential antiviral compounds isolated from these plants.

Role of Gut Microbiome in Autism Spectrum Disorder and Its Therapeutic Regulation
(Daffodil International University, 2022-07-18) Taniya, Masuma Afrin; Chung, Hea-Jong; Mamun, Abdullah Al; Alam, Safaet; Aziz, Md. Abdul; Emon, Nazim Uddin; Islam, Md. Minarul; Hong, Seong-T shool; Podder, Bristy Rani; Mimi, Anjuman Ara; Suchi, Suzia Aktar; Xiao, Jian
Autism spectrum disorder (ASD) is a neurological disorder that affects normal brain development. The recent finding of the microbiota–gut–brain axis indicates the bidirectional connection between our gut and brain, demonstrating that gut microbiota can influence many neurological disorders such as autism. Most autistic patients suffer from gastrointestinal (GI) symptoms. Many studies have shown that early colonization, mode of delivery, and antibiotic usage significantly affect the gut microbiome and the onset of autism. Microbial fermentation of plant-based fiber can produce different types of short-chain fatty acid (SCFA) that may have a beneficial or detrimental effect on the gut and neurological development of autistic patients. Several comprehensive studies of the gut microbiome and microbiota–gut–brain axis help to understand the mechanism that leads to the onset of neurological disorders and find possible treatments for autism. This review integrates the findings of recent years on the gut microbiota and ASD association, mainly focusing on the characterization of specific microbiota that leads to ASD and addressing potential therapeutic interventions to restore a healthy balance of gut microbiome composition that can treat autism-associated symptoms.
