Abstract
Three novel trifluoromethylated compounds were designed and synthesized by reacting trifluoroacetimidoyl chloride derivatives with acetamidine hydrochloride or thiourea in the presence of potassium carbonate or sodium hydrogen carbonate as a base. In vitro and in vivo assays demonstrated the efficacy of the tested compounds in controlling root-knot nematode disease on pistachio rootstocks caused by Meloidogyne incognita. Bis-trifluoromethylated derivatives, namely N,N''-thiocarbonylbis(N'-(3,4-dimethylphenyl)-2,2,2-trifluoroacetimidamide) (compound A1), showed high efficacy as novel and promising nematicides, achieving up to 78.28% control at a concentration of 0.042 mg/liter. This effect is attributed to four methyl and two trifluoromethyl groups. In the pre-inoculation application of compound A1, all three concentrations (0.033, 0.037, and 0.042 mg/liter, and Velum) exhibited a higher level of control, with 83.79, 87.46, and 80.73% control, respectively. In the microplot trials, compound A1 effectively reduced population levels of M. incognita and enhanced plant growth at a concentration of 0.037 mg/liter. This suggests that compound A1 has the potential to inhibit hedgehog protein and could be utilized to prevent the progression of root-knot disease. Furthermore, the molecular docking results revealed that compounds A1 and A3 interact with specific amino acid residues (Gln60, Asp530, Glu70, Arg520, and Thr510) located in the active site of hedgehog protein. Based on the experimental findings of this study, compound A1 shows promise as a lead compound for future investigations.

Abstract
Glycals (carbohydrate enol-ethers) have enjoyed profound applications in organic synthesis for more than a century. They not only serve as versatile glycosyl donors or as substrates for Ferrier rearrangement, but also find extensive synthetic applications especially as a "chiral pool" for accomplishing the synthesis of a variety of natural and biologically important compounds. As cyclic enol ethers, they demonstrate high reactivity and are among the most and variously transformable monosaccharide derivatives. The uniqueness of the reactivity of glycals is that they can be synthetically tuned to get a library of derivatives through stereo- and regioselective introduction of a variety of functional groups at C1, C2, C3 as well as C4 carbons of the sugar. We have developed a practical approach for stereoselective mono- and diamination of glycals and over the years utilized these scaffolds for the synthesis of a variety of biologically important nitrogen heterocycles and carbocycles through a "Diversity Oriented Approach". Our synthetic strategy in this direction mainly relied on the cleavage of ring O-C bond of the sugar followed by an "intramolecular recombination" reaction. Utilizing this strategy, we have accomplished the synthesis of several biologically important natural products, their analogues and related unnatural derivatives. Examples of such compounds reported from our group include polyhydroxypyrrolidines, DMDP, anisomycin, steviamine, pochonicine, conduramines, bulgecinine, aminocyclitols, azepanes, 4-hydroxy-D-proline, azanucleosides and their analogues. A personal account highlighting these syntheses is presented here.

Abstract
Objectives: Hepatocellular carcinoma is one of the most frequent cancers worldwide, for the treatment of which
various therapy protocols and drugs have been introduced; however, none of them has suppressed cancer tissues
completely. New research programs have been developed on cancer and the accompanied effects of novel synthesized
compounds on cancer cell lines. Our latest reports on the molecular basis of cancer revealed a pattern of changes in
gene expression triggered in the cancer pathway. Methods: HepG2 cell lines were cultured under similar conditions
in both test and control groups. The IC50 concentration of the (2R, 4S)-N-(2, 5-difluorophenyl)-4-hydroxy-1-(2, 2,
2-trifluoroacetyl) pyrrolidine-2-carboxamide compound was used in the treatment group. After 48 hours from the
culture, the expressional profiles of apoptosis pathway genes (84 genes) were studied using the PCR array method.
Results: The findings demonstrated that the expression of some apoptosis-related genes pertaining to TNF, BCL2,
IAP, and caspase families was regulated by (2R, 4S)-N-(2, 5-difluorophenyl)-4-Hydroxy-1-(2, 2, 2-Trifluoroacetyl)
Pyrrolidine-2-Carboxamide. In the same vein, an alteration was observed in the expression of both pro-apoptotic and
anti-apoptotic genes associated with the extrinsic and intrinsic apoptosis signaling pathways. Conclusions: According
to the data obtained, the pyrrolidine-2-carboxamide compound was demonstrated to be able to regulate the apoptotic
activities of HepG2 cells by affecting both pro-apoptotic and anti-apoptotic relevant genes.

Abstract
Background: Acute myeloblastic leukemia (AML) is a clonal disorder due to bone marrow failure and uncontrolled proliferation of myeloid lineage. Acute promyelocytic leukemia (APL) is a subtype of AML. Heterocyclic compounds, such as indole, are considered as attractive candidates for cancer therapy, due to their abundance in nature and known biological activity. Sal-like protein (SALL4) is a zinc finger transcription factor involving in the multi-potency of stem cells, in the NB4 cell line. This study was aimed to evaluate the effects of basal indole and its new derivative, 2-(1-((2, 4-Aril)imino)-2,2,2-trifluoroethyl) phenyl-1H Indole-3- carbaldehyde (TFPHC), on the expression of SALL4. Methods: Cells were cultured and treated with different concentrations (75, 150, and 300 µg/mL) of the new indole derivative and DMSO, as a vehicle control, for 24 and 48 hours. Cell proliferation was evaluated by using Trypan blue exclusion and MTT assays. The percentage of apoptotic cells was determined by flowcytometry analysis using the Annexin V/PI apoptosis detection kit; mRNA expression of SALL4 was studied using absolute quantitative RT-PCR. Results: Our findings demonstrated the effects of new indole derivatives on SALL4 mRNA expression. Expression of SALL4 mRNA was significantly decreased at 75, 150, and 300 µg/mL concentrations. Conclusion: SALL4 plays a role in the survival of APL cells. SALL4 expression could be suppressed by the novel indole derivative. Additionally, SALL4 gene suppression can serve as a target in APL therapy.
