The use of phytochemicals in control of human diseases have been considerable public and scientific interest in current days. Syringic acid (SA), a phenolic compound often found in fruits and vegetables and which is synthesized via shikimic acid pathway in plants. It shows a wide range of therapeutic applications in prevention of diabetes, CVDs, cancer, cerebral ischemia; as well as it possess anti-oxidant, antimicrobial, anti-inflammatory, antiendotoxic, neuro and hepatoprotective activities.

G-protein coupled receptor (GPR120) is an omega-3 fatty acid receptor that inhibits macrophage-induced tissue inflammation. Recent studies revealed GPR120 promotes colorectal carcinoma through modulation of VEGF, IL-8, PGE2, and NF-kB expression. However, three-dimensional structure of GPR120 is not yet available in Protein Data Bank (PDB).

The molecular mechanism of small molecules/peptides involved in the BAX activation was remain unknown. The present focus of the study is to identification and development of novel molecules which are precisely activates BAX mediated apoptosis.

In the current work, we describe synthesis, characterization, DFT, docking of syringic acid (SA) and analogues (SAA1 and SAA2) and biological effects were studied. Syringic acid and its analogues were docked for the first time with the crystal structures of β5 proteasome of diverse eukaryotic organisms.

In recent years enzymes associated with the rhamnose pathway in Mtb have attracted attention as drug targets. The present work is on α-D-glucose-1-phosphate thymidylyltransferase (RmlA), the first enzyme involved in the biosynthesis of L-rhamnose, of Mtb cell wall.

Evasion of apoptosis is one of the hallmarks of cancer, relevant to tumorigenesis as well as resistance to cytotoxic drugs, and deregulation of Bcl-2 proteins was observed in many cancers. Since Bax-mediated induction of apoptosis is a crucial mechanism in cancerous cells, we aimed at conducting in silico analysis on Bax in order to predict the possible interactions for anticancer agents.

Naphthoquinone is synthesized from chorismate of the shikimate pathway in microorganisms. Due to its absence in humans and animals, menaquinone biosynthesis has been an attractive target for development of antibiotics against a number of important microbial pathogens, such as Mycobacterium tuberculosis (Mtb).

Resveratrol (RESL) is a naturally occurring polyphenolic compound in food stuffs such as peanuts, seeds, berries, grapes, and beverages (red wine). RESL has received significant attention due to a plethora of in vitro and in vivo reports on its cancer chemopreventive and therapeutic properties.

The potential use of resveratrol in cancer chemoprevention or chemotherapy settings has been hindered by its short half-life and low bioavailability. Considering the above remarks, using resveratrol as a prototype, we have synthesized two derivatives of resveratrol.

Screening for nutrigenetic traits in silkworm, Bombyx mori L. (Lepidoptera: Bombycidae) is an essential prerequisite for better understanding and development of nutritionally efficient breeds/hybrids, which show less food consumption with higher efficiency conversion.

In the present work a unique enzyme of Mtb orotidine 5' monophosphate decarboxylase (Mtb-OMP Decase) is selected as drug target due to its indispensible role in biosynthesis of pyrimidines. The present work is focused on understanding the structural and functional aspects of Mtb-OMP Decase at molecular level.

One third of the world's population is infected with Mycobacterium tuberculosis (Mtb), the etiologic agent of TB. The bacterial enzyme MurA catalyzes the transfer of enolpyruvate from phosphoenolpyruvate (PEP) to uridine diphospho-N-acetylglucosamine (UNAG), which is the first committed step of bacterial cell wall biosynthesis.
View Article and Find Full Text PDFTuberculosis (TB) is still a major public health problem, compounded by the human immunodeficiency virus (HIV)-TB co-infection and recent emergence of multidrug-resistant (MDR) and extensively drug resistant (XDR)-TB. In this context, aspartokinase of mycobacterium tuberculosis has drawn attention for designing novel anti-TB drugs. Asp kinase is an enzyme responsible for the synthesis of 4-phospho-L-aspartate from L-aspartate and involved in the branched biosynthetic pathway leading to the synthesis of amino acids lysine, threonine, methionine and isoleucine.
