The bergamot’s peel contains flavonoids and pectins, a potent source of natural antioxidant/anti-inflammatory

phytochemicals. 12 The bergamot’s extract is found to be valuable in curing beta-thalassemia disease. Its extract has the ability to maintain differentiation of K562 cells and induction of erythroid production. Bergamot extract contains bergapten, bergamottin and citropten. Bergapten and citropten enhance the HbF level in K562 cells. Bergamot extract is less efficient in inducing erythroid cell differentiation and its activation value for erythroid differentiation is found to be same as hydroxyurea. Bergapten and citropten are responsible for erythroid differentiation and their biological activity is similar to that of ara-C and mithramycin. The biological activity of different bergamot extracts and the natural compound GDC-0199 ic50 have been checked by using three experimental cell systems (a) human leukemic K562 cell line (b) K562 cell clones, and (c) human erythroid progenitors isolated from normal donors. This approach may prove useful for identifying molecules capable of inducing HbF production in erythroid precursors (derived from normal donors and beta-thalassemic patients). 13

Romidepsin is commonly referred by different names such as FK228, NSC 630176, FR 901228, istodax and depsipeptide. Romidepsin is a pentapeptide extracted from Chromobacterium violaceum found in the Japanese soil sample. Its chemical

structure consists of four different amino acids (l-valine, d-valine, Z-dehydrobutyrine, buy MG-132 d-cysteine) and also (3S,4E)-3-hydroxy-7-mercapto-4-heptenoic acid. 14 The experimental results have shown that romidepsin is a potent inducer of HbF. It is effective even in picomolar concentration. It has been observed that when BFU-e (burst forming unit erythroid) cells are cultured in the presence of romidepsin of 100 pM concentration, the amount of F-erythroblasts gets increased from 13.3% to 34.9%. 15 Although romidepsin has many therapeutic applications but its production yield is very low. 14 Wheatgrass (Triticum aestivum) is an essential part of Indian culture since ages. 16 It belongs oxyclozanide to the Poaceae family whose members are generally grasses. The use of T. aestivum L. has been cited in Ayurveda, an Indian herbal medicine system. This grass has many beneficial properties and is known for its diuretic, laxative, antibacterial, antioxidant, wound healing properties. It prevents and suppresses conditions like Pitta and Kapha. Now-a-days, it is used to optimize the level of blood sugar in diabetic mellitus patients. 17 Wheatgrass is called green blood due to the presence of high amount of chlorophyll content in it. Chlorophyll is the key chemical constituent present in wheatgrass. The compounds, chlorophyll and hemoglobin are similar in structure as both contain a tetrapyrrole ring.
