In vitro cytotoxicity, in vivo pharmacokinetic studies and tissue distribution studies of multifunctional citric acid dendrimers using the drug Cytarabine
No full text<p>Dendrimers are considered the emerging polymeric architectures, known for their well defined molecular-weight, polydispersity, uniformity and high-surface functionality. These nano-architectures are capable of encapsulating low-high molecular-weight drug moieties in their interior or exterior through covalent bonding and host-guest interactions. Further, large surface volume made researchers to implicate dendrimers in biomedical and therapeutic applications. Regardless of the massive applications, sometimes its use is limited because of the cytotoxicity produced. Considering this, the present research is focused on the synthesis and PEGylation of citric acid dendrimers. PEGylation is an act of conjugating polyethylene glycol to dendrimers that completely eliminates the toxicity issues associated with dendrimers and render them biocompatible. Cytarabine was loaded in the dendritic architecture to target specifically the tumor cells. Dendrimers are made tumor specific by incorporating certain agents that get cleaved in tumor environment. Synthesized dendrimers were studied for its effect on acute cytotoxicity, tissue-distributions and pharmacokinetic parameters.</p></jats:p

DRUG POLYMORPHISM IDENTIFICATION USING FOURIER TRANSFORM-RAMAN SPECTROSCOPY: A COMPARATIVE STUDY OF LAMIVUDINE AND FINASTERIDE DRUGS
Get PDFObjectives: Maintaining the quality of the pharmaceutical drug product during its shelf life is highly desirable. The crystalline form of the drug having the great thermodynamic stability is essential for the manufacturers in pharmaceutical industry in view of their profit and also for the safety of the customer. Many pharmaceutical drugs have the tendency to exhibit polymorphism which is unwanted for pharmaceutical companies, where they have experienced market shortages due to these unpredicted polymorphic and/or pseudomorphic changes. The property of a drug exhibiting more than one crystal form is considerably regarded as polymorphism and each of the crystalline form has its own physicochemical properties, namely, solubility, heat capacity, melting point, and sublimation point. To relieve this ultimate effect on the drug quality and stability, a prior detection of polymorphism in the final dosage form is highly recommended. Hence, many analytical techniques have been proposed for the detection of polymorphism in pharmaceutical drug products.
Methods: Fourier transform (FT)-Raman spectrometer is used for the investigation of drug polymorphism and the instrument is advanced with charge coupled device detectors, ease of sample preparation and handling, mitigation of sub-sampling problems using different geometric laser irradiance patterns and having different optical components of Raman spectrometers.
Results: In this work, we carefully studied the Raman spectral patterns for Lamivudine as well as Finasteride drug substances for the detection of polymorphism. Further, we have highlighted the advantages of FT-Raman spectroscopy over other polymorphism detection techniques. For example, Raman spectra showed invariably sharp, well resolved bands compare to IR spectra due to the minor contribution of overtone vibrations in Raman spectra, resulting in much less broadening and a better resolution of bands. Besides, Raman spectroscopy does not suffer from the sampling problems that are common in X-ray powder diffraction, where preferred orientation and specimen displacements are serious restrictions for the application of quantitative method.
Conclusion: Here, in this paper, we are presented and compared the experimental results regarding the detection of polymorphism in Lamivudine and Finasteride drugs using FT-Raman spectroscopy, to illustrate the advantages of the technique in the detection of polymorphism over other techniques
Differential Perspectives Between miRNA and lncRNA in Light of Biogenesis and Functions: A Review
No full textThe central dogma is suggested that deoxyribonucleic acid is translated into ribonucleic acid (RNA) and then into protein. It is considered that 2–3% of the genomic DNA in a functionally active cell, is transcribed to protein-coding RNA. The presence of noncoding transcripts has been neglected many a time as cellular DNA and transcript noises, however, increasing proof proposes that a very important part of these non-coding transcripts is functionally effective as RNA molecules. The non-coding transcripts of up to 100 bases are known as small non-coding RNA that comprises tRNA, miRNA, snoRNA, piwi-interacting RNA (pi-RNA), etc. Interestingly, rRNA features about 6.9 kb, though these are not considered long-non-coding RNAs. However, RNA molecules that are over 200 bases long (ranging between 0.8 to 10 kb) are known as long non-coding RNA (lncRNA). It does not have open reading frames (with some exceptions), 3`- untranslated regions (3’-UTRs), and these RNAs are devoid of any translation-termination regions. However, these may be capped, spliced, and polyadenylated as RNA molecules and play a major role in factor regulation, neoplastic cell invasion, chromatin granule transforming, and cell differentiation. Downregulation of lncRNA is responsible for numerous diseases in mammals. miRNAs are mature transcripts of 22 nt in length and function as antisense regulators of other RNAs. They play role in post-transcriptional factors and are involved in differentiation, proliferation, immune response, cell growth, and caspase-mediated cell death. Downregulation in miRNA expression has a necessary role in many diseases, together with cancers
