Curcumin, a natural yellow phenolic compound, is present in various types of herbs, particularly in Turmeric, Curcuma longa Linn. (Zingiberaceae family) rhizomes. Curcumin is a polyphenolic natural compound with diverse and attractive biological activities. In the last decade curcumine and its various synthetic analogues have been prepared and evaluated for various pharmacological activities that prove it as a lead molecule against several biological targets. It is a natural antioxidant and exhibited many pharmacological activities such as anti-inflammatory, anti-microbial, anticancer, anti-Alzheimer in both preclinical and clinical studies. Moreover, Curcumin and its analogues have anti-tubercular, cardioprotective, anti-diabetic, hepatoprotective, neuroprotective, nephroprotective, antirheumatic and anti-viral activities. The substitutions of 1,6-heptadiene linkage moiety via carbonyl group sustituion and addition of heterocyclic linker; isoxazole, 1H-pyrazole, cyclopentanone, piperidin-4-one, N-methylpiperidin-4-one enhance biological activities. The structure activity relationship of various curcumin analogues is studied for medicinal purposes and it reveals that monocarbonyl linkage analogues have anticancer properties. The current review gives an insight of the history, chemistry, analogues and most interesting in vitro and in vivo studies on the biological effects of Curcumin and its analogues.

Proteasomes of pathogenic microbes have become attractive targets for anti-infectives. Coevolving with its human host, Mycobacterium tuberculosis (Mtb) has developed mechanisms to resist host-imposed nitrosative and oxidative stresses. Genetic deletion or pharmacological inhibition of the Mtb proteasome (Mtb20S) renders nonreplicating Mtb susceptible to reactive nitrogen species in vitro and unable to survive in the lungs of mice, validating the Mtb proteasome as a promising target for anti-Mtb agents. Using a structure-guided and flow chemistry-enabled study of structure-activity relationships, we developed phenylimidazole-based peptidomimetics that are highly potent for Mtb20S. X-ray structures of selected compounds with Mtb20S shed light on their selectivity for mycobacterial over human proteasomes.

Pharmacokinetics (PK) is the study of the absorption, distribution, metabolism, and excretion (ADME) processes of a drug. Understanding PK properties is essential for drug development and precision medication. In this review we provided an overview of recent research on PK with focus on the following aspects: (1) an update on drug-metabolizing enzymes and transporters in the determination of PK, as well as advances in xenobiotic receptors and noncoding RNAs (ncRNAs) in the modulation of PK, providing new understanding of the transcriptional and posttranscriptional regulatory mechanisms that result in inter-individual variations in pharmacotherapy; (2) current status and trends in assessing drug?drug interactions, especially interactions between drugs and herbs, between drugs and therapeutic biologics, and microbiota-mediated interactions; (3) advances in understanding the effects of diseases on PK, particularly changes in metabolizing enzymes and transporters with disease progression; (4) trends in mathematical modeling including physiologically-based PK modeling and novel animal models such as CRISPR/Cas9-based animal models for DMPK studies; (5) emerging non-classical xenobiotic metabolic pathways and the involvement of novel metabolic enzymes, especially non-P450s. Existing challenges and perspectives on future directions are discussed, and may stimulate the development of new research models, technologies, and strategies towards the development of better drugs and improved clinical practice.

Two fluorescent derivatives of the M1 muscarinic selective agonist AC-42 were synthesized by coupling the lissamine rhodamine B fluorophore (in ortho and para positions) to AC42-NH2. This precursor, prepared according to an original seven-step procedure, was included in the study together with the LRB fluorophore (alone or linked to an alkyl chain). All these compounds are antagonists, but examination of their ability to inhibit or modulate orthosteric [3H]NMS binding revealed that para-LRB-AC42 shared several properties with AC-42. Carefully designed experiments allowed para-LRB-AC42 to be used as a FRET tracer on EGFP-fused M1 receptors. Under equilibrium binding conditions, orthosteric ligands, AC-42, and the allosteric modulator gallamine behaved as competitors of para-LRB-AC42 binding whereas other allosteric compounds such as WIN 51,708 and N-desmethylclozapine were noncompetitive inhibitors. Finally, molecular modeling studies focused on putative orthosteric/allosteric bitopic poses for AC-42 and para-LRB-AC42 in a 3D model of the human M1 receptor.

Highly effective indium(III)-catalyzed reductive bromination or iodination of a variety of carboxylic acids with 1,1,3,3-tetramethyldisiloxane (TMDS) and a source of bromine or iodine is described. This functional group interconversion has high tolerance for several functional groups, such as halogens, a hydroxy group, a nitro group, an olefin part, and a sulfide moiety. This indium catalytic system is also applicable to the reductive iodination of aldehyded, acyl chlorides, and esters. Furthermore, this reducing system can be applied to the one-pot synthesis of alkyl halides and amine derivatives via the addition of nucleophiles. Insight into the reaction mechanism was gained via the time course of 1H and 13C NMR monitoring experiments and the corresponding stepwise reactions.

Background: Curcumin is a polyphenolic natural compound with multiple targets that used for the prophylaxis and treatment of some type of cancers like cervical and pancreatic cancers. Some recent patent for curcumin for cancer has also been reviewed. Objective: In this study, ten new curcumin derivatives were designed and synthesized and their cytostatic activity evaluated against the Hela and Panc cell lines that some of them showed more activity than curcumin. Method: In the present study, a series of mono-carbonyl derivatives of curcumin were designed and prepared. The details of the synthesis and chemical characterization of the synthesized compounds are described. The cytostatic activities of the designed compounds are assessed in two different tumor cell lines using MTT test. Results: In vitro screening for human cervix carcinoma cell lines (Hela) and pancreatic cell lines (Panc-1) at 24 and 48 hour showed that all the analogs possessed good activity against these tumor cell lines and compounds 5a, 5c and 6 with high potency can be used as a new lead compounds for the designing and finding new and potent cytostatic agents. Docking studies indicated that compound 5c readily binds the active site of human glyoxalase I protein via two strong hydrogen bonds engaging residues of Glu-99 and Lys-156. Conclusion: Our results are useful in guiding a design of optimized ligands with improved pharmacokinetic properties and increased of anti-cancer activity vs. the prototype curcumin compound.
