Immunoendocrine regulation of energy homeostasis and male reproduction

Male reproduction and its intricate neuroimmunoendocrine regulations open a wide scope of scientific interventions. Male infertility, being responsible for about half of the overall global infertility cases, represents a complex pathophysiological mechanism. Crosstalk among the endogenous immune and endocrine mediators may affect male gonadal functions. Since male reproduction is fine-tuned by orchestrated regulation of reproductive hormones and immune regulators, a better understanding of these chemical regulations will potentiate further research in this direction.

This issue aims to summarize the current knowledge on the hormonal and immunological regulations of male reproductive functions in physiological and pathophysiological conditions of male reproduction.

Potential topics include but are not limited to the following:

  • Energy homeostasis  and male reproduction
  • Immunoendocrine regulation of male reproductive functions
  • Adipokines and energy metabolism in male fertility
  • Obesity and male infertility: energy imbalance to inflammation
  • Endocrine regulation of epigenetics of reproductive tract inflammation
  • Altered energy metabolism and immune regulation in aged men

Keywords: 4-methyl-1H-isochromen-1-one, 1,1-biphenyl-4,4-diamine, Antibacterial activity, anti-microbial activity


Selected novel β-lactam and thiazolidinone derivatives have been synthesized by the reaction of 4-methyl-1H-isochromen-1-one with 1,1-biphenyl-4,4-diamine, followed by the reaction with substituted benzaldehyde and further by the reaction with chloroacetyl chloride (for β-lactam type) and with thioglycolic acid (for thiazolidinone type) respectively . All the compounds were characterised by 1H NMR, IR and mass spectroscopy. These compounds were screened for in-vitro antimicrobial activity against Staphylococus aureus, E. coli, Pseudomonas aeruginosa strain. Some compounds have shown very good efficacy against antibacterial strain.

In this paper, we report the design, synthesis, in-silico, and in-vitro evaluations of a series of coumarin-phenylthiazole conjugates to inhibit cholinesterase enzymes. The coumarin and phenylthiazole derivatives have been synthesized separately, and further combined through covalent amine bond linkage. The synthesized compounds showed more inhibition towards BuChE than AChE, where 4-(3-bromophenyl)-1,3-thiazol-2-amine (7i) exhibited the strongest inhibition against BuChE with an IC50 value of 3.54 μM. For the conjugates, 3-{2-[4-(3-nitrophenyl)thiazol-2-ylamino]acetyl}chromen-2-one (8j) exhibited strongest inhibition with an IC50 value of 46.47 μM.  The better inhibition activities towards BuChE are also shown by 3-bromo and 2-fluoro derivatives. It was also observed that the substitution at 3-position, on phenylthiazole moiety produced better results against BuChE than 4-substituted counterparts.

Critical evaluation of pharmaceutical rational design of Nano-Delivery systems for Doxorubicin in Cancer therapy

Critical evaluation of pharmaceutical rational design of Nano-Delivery systems for Doxorubicin in Cancer therapy

Published in: Journal of Materials NanoScience


Running title: Rationale of designing of nanoparticular delivery systems and impact of chemistry used with doxorubicin for anti-cancer therapy

Keywords: Adriamycin, Cancer Drug, CPP, Drug Delivery System, Lipophilic Dox, TAT peptide


Doxorubicin (Dox), an antineoplastic drug, has been extensively used for the treatment of different cancers. Dox is hydrophilic and therefore distributes to normal organs at a faster rate. Due to its required high doses, it poses severe toxicity, such as cardiotoxicity and nephrotoxicity. Diverse approaches, including nanoparticulate delivery systems, have been designed and evaluated to improve its delivery to the target site and reduce toxicity to normal organs; however, this has met little success. Here in this review, we have discussed various systems (metal nanoparticles, carbon nanotubes, fullerenes, liposomes, dendrimers, cyclic peptides, and other covalent/non-covalent systems) that have been used for Dox. We have critically evaluated their designing and outcome (in vitro and in vivo) with potential applications in the clinical setting.

Chemical libraries targeting Liver Stage Malarial infection


Chemical Scaffolds Targeting liver-stage malaria parasite lifecycle

Keywords: Malaria, Liver stage, Primaquine, Atovaquone, Clinical trials


Despite the noteworthy advances in the use of chemotherapy for malaria, it continues to constantly affect large number of individuals. New molecules capable of blocking life-cycle of the parasite, preferably through targeting novel pathways and various modes of action, are increasingly becoming area of interest. Phenotypic screening of large chemical libraries is certainly one of the important criteria for the discovery of new and effective drugs. In recent years, diverse research groups including pharmaceutical industries have performed this large-scale phenotypic screening to identify the potential drug molecules. Most of the antimalarial drugs target blood-stage malarial infection and remain either less potent or ineffective against other life stages i.e. liver-stage, and the gametocyte stages of the parasite. Although, liver stage is considered as a crucial drug target, limited clinical options have significantly hampered the discovery of effective treatments. This short review presents the collection of selective molecules targeting specifically liver stage malaria parasites.

2-Methyl-1,2,3,4-tetrahydroquinolin-4-yl)pyrrolidin-2-ones (3a−g) were synthesized by one pot multicomponent aza Diels-alder reaction between N-arylimines with two molecules of N-vinyl-2-pyrrolidinone in presence of Sm(III)nitrate as catalyst in acetonitrile solvent at room temperature stirring. The photocleavage studies with 2-methyl-1,2,3,4-tetrahydroquinolin-4-yl)pyrrolidin-2-ones (3a−g) revealed that almost all derivatives exhibited effective photocleavage of pUC−19 DNA at 365 nm, The The anticancer activities of newly synthesized compounds (3a−g) were more potent than doxorubicin on MCF−7 cells. The docking of PBR receptor (1EQ1) protein with newly synthesized THQ’s (3a-g) exhibited well established bonds with one or more amino acids in the receptor active pocket.
