Tetra and pentacyclic azaphenothiazines are structures with a high broad-spectrum anticancer activity.
The phenothiazine scaffold is favorable for developing of anticancer agents, especially those bearing halogens and electron withdrawing groups bound at 2-position with enhanced biological activities with a variety of aromatic, aliphatic and heterocyclic substituents in the thiazine nitrogen. Further studies are warranted along these investigation lines to attain more active anticancer and antiprotozoal compounds with minimal to negligible cytotoxicity.

Some pathogenic bacteria can be potentially used for nefarious applications in the event of bioterrorism or biowarfare. Accurate identification of biological agent from clinical and diverse environmental matrices is of paramount importance for implementation of medical countermeasures and biothreat mitigation.
A novel methodology is reported here for the development of a novel enrichment strategy for the generally conserved abundant bacterial proteins for an accurate downstream species identification using tandem MS analysis in biothreat scenario.
Conserved regions in the common bacterial protein markers were analyzed using bioinformatic tools and stitched for a possible generic immuno-capture for an intended downstream MS/MS analysis. Phylogenetic analysis of selected proteins was carried out and synthetic constructs were generated for the expression of conserved stitched regions of 60 kDa chaperonin GroEL. Hyper-immune serum was raised against recombinant synthetic GroEL protein.

Coumarin compounds show different biological properties viz antimicrobial, antibacterial, antifungal, antioxidant, antitumor, anti-HIV, antihypertension, anticoagulant, anticancer, antiviral, anti-inflammatory, analgesics, antidiabetic, anti-depressive, and other bioactive properties. Coumarin and its derivatives possess anticancer activity against different types of cancers such as prostate, renal, breast, laryngeal, lung, colon, CNS, leukemia, malignant melanoma. In this review, current developments of coumarin based anticancer agents viz simple coumarin, furanocoumarin, pyranocoumarin, pyrone-substituted coumarin and their important derivatives have been discussed. The coumarin-triazole, coumarin-chalcone, coumarin-thiosemicarbazone derivatives and coumarin-metal complexes have been found to more potent than coumarin. Hence, further study and structural improvement on coumarin and its derivatives may lead to the design and development of more potent anticancer agents.Cardiovascular diseases (CVD) are known to be the world's leading cause of death, and different factors are known to increase the risk of death, including aging, mainly due to increased oxidative stress and inflammation observed in older people. Acute myocardial infarctions and cerebrovascular accidents belong to CVD, and are the ones that cause the most deaths and disabilities, where greater platelet activation plays an important role in pathophysiology. These diseases are more prevalent in older people, which have a clear relationship with increased platelet function and are strongly related to aging. Platelet function is affected by diet, which varies in its requirements and characteristics according to age. Coffee belongs to the family of diet elements that can alter platelet function and an increase in coffee consumption with advancing age and a U-shaped correlation with the risk of CVD have been reported. However, the effect of coffee consumption and its bioactive compounds on platelet function and aging presents controversial evidence, and therefore, a complex effect is not fully elucidated in the cardiovascular system. This review focuses on the relationship between coffee consumption (and its constituent bioactive compounds), and platelet function, and aging.Aging is an unavoidable process, leads to cell senescence due to physiochemical changes in an organism. Anti-aging remedies have always been of great interest since ancient times. The purpose of anti-aging activities is to increase the life span and the quality of life. Anti-aging activities are primarily involved in the therapies of age-related disorders such as Parkinson's disease (PD), Alzheimer's disease (AD), cardiovascular diseases, cancer and chronic obstructive pulmonary diseases. These diseases are triggered by multiple factors that are involved in numerous molecular pathways including telomere shortening, NF-κB pathway, adiponectin receptor pathway, insulin and IGF signaling pathway, AMPK, mTOR and mitochondria dysfunction. Natural products are known as effective molecules to delay the aging process through influencing metabolic pathways and thus ensure an extended lifespan. Abemaciclib These natural compounds are being utilized in drug design and development through computational and high throughput techniques for effective pro-longevity drugs. A comprehensive study of natural compounds demonstrated with their anti-aging activities along with databases of natural products for drug designing was executed and summarized in this review article.
Alzheimer's disease (AD) is a multifactorial neurodegenerative disease and a drug which targets a single protein will not provide a cure for the disease. Currently available drugs for AD are all palliative rather than curative. FDA approved only five drugs for the treatment of AD, which includes tacrine, donepezil, galantamine, rivastigmine, and memantine. Tacrine discontinued due to its hepatotoxicity. The lack of therapeutic effectiveness of the single-target drugs and multifactorial etiology of AD leads to the design of multitarget directed ligands for AD.
The researchers in this field are constantly putting effort for the development of a drug for the exact cure of this disease by exploring the different biological targets associated with AD. The present review comprises various multitarget approaches and tools used for finding out a lead compound or a new drug, which will give a cure for AD.
We have scrutinized and reviewed 75 research articles published in various peer reviewed journals in the last two decades in the field of multi target directed ligand approaches for the discovery of a new therapeutic agent for AD.
