Oleanolic acid (OA) is a naturally occurring pentacyclic triterpenoid with multifarious actions. Chief among them is the anti-inflammatory effect it exerts when taken orally; however, the underpinning mechanisms of such effects have not yet been fully explored.

In the present study, we evaluated the anti-inflammatory and anti-nociceptive effect of OA by injecting it directly into the knee joint using an animal model of osteoarthritis. Behavioral and electrophysiological studies were conducted to determine whether OA exerts a direct modulatory effect on primary sensory afferents that could lead to a decrease in pain-related behaviors and inflammatory responses. Rats were divided into two main groups a pre- and a post-treatment group. Knee joint inflammation was induced by injecting a mixture of 3% kaolin and carrageenan (K/C). In the pre-treatment groups, two different doses of OA [5 mg/ml (n=5) and 30 mg/ml (n=4); 0.1 ml per injection] were administered into the synovial cavity of the knee joint before induction of inflammation. In the post-treatment group, rats received only one dose [5 mg/ml (n=5)] of OA after induction of inflammation.

Results indicate that intra-articular injection of OA improves motor coordination and attenuates nociceptive behav-ior and inflammatory reactions. More importantly, we observed a direct depolarizing action of OA on articular sensory fi-bers, a crucial mechanism that activates descending inhibitory pathways and controls incoming nociceptive signals to the spinal cord.

Overall, our findings suggest that OA can be used as preventive and therapeutic approach for the management of osteoarthritis.

Parkinson’s disease (PD) is a progressive neurodegenerative disease manifested by core symptoms of loss of motor control and postural instability. Loss of dopaminergic neurons is the cause of PD, thus enhancing dopamine level by pharmacological treatment is one of the key treatment strategies for PD. However, limitations of current treatment strategies open the possibility of novel drug candidates for the treatment of PD.

To investigate the anti-PD potential of Harmine and Harmaline. We aim to evaluate the therapeutic potential of Harmine and Harmaline by in-silico approaches; molecular docking, pharmacokinetic and Prediction of Activity Spectra for Substances (PASS) analysis were used for evaluating the therapeutic potential of Harmine and Harmaline and standard drug levodopa (L-DOPA).

Auto dock vina was used for molecular docking of all three compounds against D2- and D3- dopamine receptors. The pharmacokinetics (PKs) and toxicity profile were predicted by pkCSM and the pharmacological activity was predicted by PASS analysis.

Molecular docking showed a higher binding affinity of Harmine and Harmaline as compared to L-DOPA, and these results were supported by in-silico pharmacokinetic and toxicity profiling. Moreover, PASS analysis showed anti-PD activi-ty of Harmine and Harmaline.

Harmine and Harmaline exhibit higher binding affinity towards D2- and D3- dopamine receptors compared to L-DOPA, and PKs and toxicity profile support their potential as drug candidates for PD therapy.

To formulate and preliminary evaluated polysaccharide based mucoadhesive floating tablets of Cinnarizine.

Gastro-retentive drug delivery systems has proved to be a successful approach to enhance the gastric residence with site specific targeting for achieving local or generalized effect. Various patents has also been filed globally employing gastro-retentive approach.

The study is designed to explore the mucoadhesive and low density characteristics of corn fibre gum (CFG) for preparation of gastro-retentive floating tablets of cinnarizine.

Floating tablets were prepared by direct compression technique using different concentrations of CFG (45, 50, 60% w/w). Selleckchem CDK inhibitor The formulated floating tablet batches were evaluated for their hardness, friability, drug content, floating duration/ lag time, swelling behavior, bioadhesive strength and in vitro drug release.

Mucoadhesive strength was found to increase with an increment in the polysaccharide concentration. Swelling index was found to increase both with the ings, CFG could be concluded to possess potential binder, release retardant and mucoadhesive characteristics which could be successfully employed for the formulation of gastro-retentive floating tablets.This paper examines the potential link between COVID-19 and the presence of comorbidities and assesses the role of inflammation in this correlation. In COVID-19 patients, the most frequently associated diseases share a pathogenic inflammatory basis and apparently act as a risk factor in the onset of a more severe form of the disease, particularly in adulthood. However, in children, the understanding of the underlying pathogenic mechanisms is often complicated by the milder symptoms presented. A series of theories have, therefore, been put forward with a view of providing a better understanding of the role played by inflammation in this dramatic setting. All evidence available to date on this topic is discussed in this review.

The present study was conducted to evaluate the antimicrobial effects of the recombinant chimer present in the lactoferrampin-lactoferricin [LFA-LFC] derived from the camel milk on some oral bacteria responsible for dental caries and endodontic failures.

The antimicrobial activity was assessed on the Streptococcus mutans [ATCC 35668], Streptococcus salivarius [ATCC 9222], Streptococcus oralis [ATCC 35037], and Enterococcus faecalis [ATCC 29212], using the microbroth dilution method. The cytotoxicity analysis was done through the MTT method on the human gingival fibroblasts. The data were reported using the descriptive methods, and were analyzed by the one-way analysis of variance (ANOVA) and Tukey’s honestly significant difference (HSD) test.

Results showed that the chimeric peptide had the highest bacteriostatic effect on S. salivarius with the lowest minimum inhibitory concentration value of 1.22 μg/Ml. Also, LFA-LFC chimer was more effective against S. mutans and S. salivarius compared to using 0.2% chlorhexidine mouthwash.
