Novel efficacy of pregnane and flavonoid glycosides from Desmidorchis flava in in vivo nociceptive and inflammatory paradigms and their target prediction by cheminformatics approach Ajmal Khan, Hamdy Kashtoh, Najeeb Ur Rehman, Muhammad Shahid, Irfan Ullah, Asaad Khalid, Afnan Jan, Sobia Ahsan Halim, Kwang-Hyun Baek, Ahmed Al-Harrasi Natural Product Research, 2025 Inflammation is associated with multiple life-threatening conditions. Desmidorchis flava is an edible plant and traditionally used for managing various diseases. Three novel molecules, namely desmiflavaside-C (1), nizwaside (2), and desmiflanoside (3) were isolated from Desmidorchis flava, and their structures were confirmed by mass spectrometry and through reported literature. These compounds were in vivo examined for antinociceptive (tonic visceral nociception) and anti-inflammatory (carrageenan induced paw edema) activities. Significant antinociceptive potential was demonstrated by compound 1 at 0.5 and 1 mg/kg doses followed by compounds 2 and 3. At similar doses, significant anti-inflammatory activity was noted for all the tested compounds. Their antinociceptive and anti-inflammatory activities were comparable to the reference standards. In silico predicted binding modes suggests that these compounds may target allosteric sites of COX-1 and COX-2 enzymes to elicit their anti-inflammatory activities. These isolated natural products may have therapeutic potential in conditions afflicted with pain and inflammation.
Galegine, a Bioprivileged Alkaloid from Tithonia tubaeformis: Antipyretic Activity Insights Noor Ul Ain Nawaz, Muhammad Saeed, Shaheen Faizi, Irfan Ali, Muhammad Shafiq, Muhammad Shahid, Fazle Rabbi, Fahim Ullah Khan, Rabeea Sharif, Zaheer Ul-Haq, Khalid Mohammed Khan, Hassan A. Hemeg, Waleed Al Abdulmonem, Abdullah S. M. Aljohani, Abdur Rauf Current Topics in Medicinal Chemistry, 2025 Background: In continuation of our chemical and biological work on Tithonia tubaeformis, we evaluated the antipyretic activity of its extract which on fractionation gives a pure alkaloid galegine. Galegine a bioprivileged compound, is a hemiterpene bearing a guanidine group, which holds significant importance in medicinal chemistry. Biological activities such as antimicrobial, antidiabetic, anti-inflammatory, cardiovascular, anticancer, and antihypertensive, are often associated with guanidine-containing molecules. Objective: Given the biological importance of guanidine and in search of safe antipyretic agents from natural resources, an in vivo antipyretic activity of methanolic extract of T. tubaeformis and galegine was conducted to discover a potential hypothermic drug candidate from the plant. Methods: In vivo, the antipyretic activity of galegine (5, 25, and 50 mg/kg doses) and methanolic extract of T. tubaeformis (50, 100, and 200 mg/kg doses) was investigated by employing yeastinduced pyrexia in mice model. In silico molecular docking analysis involving target enzymes cyclooxygenase- 1 (COX-1), cyclooxygenase-2 (COX-2), and microsomal prostaglandin E synthase-1 (mPGES-1) was conducted. Additionally, galegine underwent ADME/T profiling using SwissADME and Protox-II tools to evaluate its bioavailability and safety profiles. Results: Both the extract and galegine showed a progressive dose-dependent reduction in body temperatures of the hyperthermic test animals. Moreover, in silico molecular docking analysis revealed significant binding affinities ranging from -3.58 to -5.41 kcal/mol. ADME/T analyses of galegine predicted its high drug-likeness and good safety profile. Conclusion: These biological and computational approaches supported T. tubaeformis in addressing pyrexia, with the isolated compound galegine emerging as a promising antipyretic agent.
Evaluation of the Ameliorative Potential of 3,5-bis(2-hydroxyethyl)-1,3,5-thiadiazinane-2-thione against Scopolamine-Induced Alzheimer’s Disease Shagufta, Gowhar Ali, Adnan Khan, Abdur Rasheed, Farah Deeba, Rahim Ullah, Muhammad Shahid, Haleema Ali, Rasool Khan, Najeebullah Shamezai, Naveed Sharif International Journal of Molecular Sciences, 2024 Alzheimer’s disease (AD) is the most common neurodegenerative disorder, marked by cognitive impairment. Currently, the available treatment provides only symptomatic relief and there is a great need to design and formulate new drugs to stabilize AD. In the search for a new anti-Alzheimer’s drug, 3,5-bis(2-hydroxyethyl)-1,3,5-thiadiazinane-2-thione (THTT), a tetrahydro-2H-1,3,5-thiadiazine-2-thione derivative, was investigated against a scopolamine-induced Alzheimer’s model. The selected test compound was administered intraperitoneally in three doses (15 mg/kg, 30 mg/kg, and 45 mg/kg). The test compound exhibited an IC50 value of 69.41 µg/mL, indicating its ability to inhibit the acetylcholinesterase enzyme. An antioxidant DPPH assay revealed that the IC50 value of the test compound was 97.75 µg/mL, which shows that the test compound possesses antioxidant activity. The results of behavior tests including the Y-maze and elevated plus maze (EPM) show that the test compound improved short-term memory and spatial memory, respectively. Furthermore, in the Morris water maze (MWM) and light/dark model, the test compound shows improvements in learning and memory. Moreover, the results of histological studies show that the test compound can protect the brain against the harmful effects of scopolamine. Overall, the findings of our investigation suggest that our chosen test compound has disease-modifying and neuroprotective activities against the scopolamine-induced Alzheimer’s model. The test compound may be beneficial, subject to further elaborate investigation for anti-amyloid disease-modifying properties in AD.
Isolation and Characterization of Lactobacillus crispatus, Lactococcus lactis, and Carnobacterium divergens as Potential Probiotic Bacteria from Fermented Black and Green Olives (Olea europaea): An Exploratory Study Ayesha Saeed, Azra Yasmin, Mehreen Baig, Khalid Khan, Md Belal Bin Heyat, Faijan Akhtar, Zahra Batool, Abeer Kazmi, Abdul Wahab, Muhammad Shahid, Muhammad Arslan Ahmed, Sidra Abbas, Abdullah Y. Muaad, Amir Shahzad, Imtiaz Ahmad Biomed Research International, 2023 Background. Table olives are becoming well recognized as a source of probiotic bacteria that might be used to create a health‐promoting fermented food product by traditional procedures based on the activities of indigenous microbial consortia present in local environments. Methodology. In the present study, the characterization of probiotic bacteria isolated from mince, chunks, and brine of fermented green and black olives (Olea europaea) was done based on morphological, biochemical, and physiological characteristics. Results. Bacterial isolates demonstrated excellent survival abilities at 25, 37, and 45°C and at a variable range of pH. However, the optimum temperature is 37 and the optimum pH is 7 for all three isolates. An antimicrobial susceptibility pattern was found among these isolates through the disc diffusion method. Most of the isolates were susceptible to streptomycin, imipenem, and chloramphenicol, whereas, amoxicillin showed resistance to these isolates, and variable results were recorded for the rest of the antibiotics tested. The growth of the isolates was optimum with the supplementation of 3% NaCl and 0.3% bile salt. The isolated bacteria were able to ferment skimmed milk into yogurt, hence making it capable of producing organic acid. Conclusion. Isolates of Lactobacillus crispatus MB417, Lactococcus lactis MB418 from black olives, and Carnobacterium divergens MB421 from green olives were characterized as potential candidates for use as starter cultures to induce fermentation of other probiotic food products.
