Abstract
The aim of this review is to discuss the development of nanostructured lipid carrier (NLC) by the application of quality by design (QbD). QbD started with the evolution of the quality concept and slow adaptation of quality guidelines, which has now become a regulatory requirement. In this review, brief history and elements of QbD including risk assessment (RA) have been discussed followed by the design of experiments (DoEs) that acts as a tool to analyze the input whose variation can optimize the output with the desired goal. NLC is a versatile delivery system as researchers widely use it to administer therapeutics with different physicochemical properties. The surface of NLC can be modified, making it a suitable delivery system with targeting potential for therapeutics. Implementation of QbD provides a high-quality robust formulation that can consistently meet the patient’s requirement throughout its life cycle without compromising the safety and effectiveness of the drug and delivery system. This review discusses QbD concepts followed by the systematic development of NLC by the application of DoE. Process analytical technology (PAT) and six sigma concepts have also been included which can benefit in the development of optimized NLC.

Abstract
Cancer is one of the leading causes of death worldwide. Chemotherapy and radiation therapy are the major treatments used for the management of cancer. Multidrug resistance (MDR) is a major hindrance faced in the treatment of cancer and is also responsible for cancer relapse. To date, several studies have been carried out on strategies to overcome or reverse MDR in cancer. Unfortunately, the MDR reversing agents have been proven to have minimal clinical benefits, and eventually, no improvement has been made in therapeutic efficacy to date. Thus, several investigational studies have also focused on overcoming drug resistance rather than reversing the MDR. In this review, we focus primarily on nanoformulations regarded as a novel approach to overcome or bypass the MDR in cancer. The nanoformulation systems serve as an attractive strategy as these nanosized materials selectively get accumulated in tumor tissues, thereby improving the clinical outcomes of patients suffering from MDR cancer. In the current work, we present an overview of recent trends in the application of various nano-formulations, belonging to different mechanistic classes and functionalization like carbon nanotubes, carbon nanohorns, carbon nanospheres, liposomes, dendrimers, etc., to overcome MDR in cancer. A detailed overview of these techniques will help researchers in exploring the applicability of nanotechnologybased approaches to treat MDR.

Abstract
The aim of the present study was to develop and characterize karanjin-loaded ethosomes-based gel formulation for enhanced topical delivery and effective therapy of skin acne. Karanjin-loaded ethosomes (K-ETH) presented a nanometric size of 140.87 ± 2.35 nm, entrapment of 71.41 ± 2.74% and enhanced permeation with 1.9 times increase in the flux and 2.4 times higher skin deposition compared to the hydro-ethanolic solution of karanjin. The DSC analysis confirmed successful entrapment of the karanjin within the ethosomes. The developed ethosomes were incorporated in the carbopol gel for adequate application on the skin surface. The ethosomal gel (K-EGF) also exhibited greater penetration in the rat skin as revealed by CLSM. The optimized K-EGF formulation was non-irritant to the skin as evident by Draize score test and histopathological examination. The highest zone of inhibition, 30.0 ± 1.52 mm and 36.22 ± 0.57 mm was produced by the K-EGF against Propionibacterium acnes and Staphylococcus epidermidis, respectively, indicating substantial antibacterial properties of the K-EGF. DPPH assay indicated its potent antioxidant effects. Substantial anti-inflammatory effects in the carrageenan-induced edema in the rat paw were evident with inhibition of rat paw edema by 66.66% and 70.37% upon application of K-EGF and standard anti-inflammatory agent, respectively. Anti-acne effects were also evident with K-EGF treatment with significant decrease in number and size of sebaceous gland units in dermis. Overall, the above findings vouch for a therapeutic opportunity to improve topical delivery of karanjin in acne treatment employing ethosomal gels as the promising carrier system.

Abstract
Skin being the largest external organ, offers an appealing procedure for transdermal drug delivery, so the drug needs to reach above the outermost layer of the skin, i.e., stratum corneum. Small molecular drug entities obeying the Lipinski rule, i.e., drugs having a molecular weight less than 500 Da, high lipophilicity, and optimum polarity, are favored enough to be used on the skin as therapeutics. Skin's barrier properties prevent the transport of macromolecules at pre-determined therapeutic rates. Notable advancements in macromolecules' transdermal delivery have occurred in recent years. Scientists have opted for liposomes, the use of electroporation, low-frequency ultrasound techniques, etc. Some of these have shown better delivery of macromolecules at clinically beneficial rates. These physical technologies involve complex mechanisms, which may irreversibly incur skin damage. Majorly, two types of lipid-based formulations, including Solid Lipid Nanoparticles (SLNs) and Nanostructured Lipid Carriers (NLCs), are widely investigated as transdermal delivery systems. In this review, the concepts, mechanisms, and applications of nanostructured lipid carriers used to transport macromolecules via transdermal routes are thoroughly reviewed and presented along with their clinical perspective.

Abstract
Effective and precise eradication of Helicobacter pylori (H. pylori) is the most promising approach to avoid H. pylori-related gastrointestinal disorders. The present study was conducted to demonstrate the efficacy of the co-delivery of hesperidin (Hesp) and clarithromycin (CLR) in nanostructured lipid carriers (NLCs) against H. pylori. We have produced a new delivery system by combining bioflavonoid Hesp and CLR NLCs to address the failure in single antibiotic therapies. Briefly, a blend of solid lipid, liquid lipid, and surfactant was used. Homogeneous NLCs with all the formulations showed a nano size and surface-negative charge and presented high in vitro stability and slow release of the drug even after 24 h. Bioimaging studies by scanning electron microscopy, transmission electron microscopy, and imaging flow cytometry indicated that NLCs interacted with the membrane by adhering to the outer cell membrane and disrupted the membrane that resulted in the leakage of cytoplasmic contents. The prepared NLCs provide sustained and controlled drug release that can be used to increase the rate of H. pylori eradication.

Abstract
In the present study, mupirocin (MP), an antimicrobial agent, was formulated as a nanostructured lipid carrier (NLC) by using a novel method named as melt emulsion ultrafiltration method. For the formulation of NLC, glyceryl monostearate and watermelon seed oil were used as solid and liquid lipids, respectively. The method was optimized for various parameters by Taguchi design of experiment and prepared NLCs were characterized for particle size, polydispersity index (PDI), shape, zeta potential, % drug loading, and in vitro release profile. The optimized NLCs were found to be smooth, monodisperse with PDI 0.229 ± 0.093. NLCs were found to have an average particle size of 139 ± 0.75 nm and +21.9 ± 0.98 mV as zeta potential. The % drug loading of optimized NLCs was found to be 59% ± 0.13%. The optimized NLCs were able to release the drug up to 24 h. The release kinetic study revealed mixed-order kinetics. Hence, it was concluded that the novel method is simple and able to fabricate MP-loaded NLCs with sustained release property and being stable in terms of particle size, PDI, and % drug loading.

Abstract
The present study aimed to develop a surface-modified biocompatible nanostructured lipid carrier (NLCs) system using polyoxyethylene (40) stearate (POE-40-S) to improve the oral bioavailability of poorly water-soluble Biopharmaceutics Classification System class-II drug like tamoxifen (TMX). Also aimed to screen the most influential factors affecting the particle size (PS) using Taguchi (L12 (211)) orthogonal array design (TgL12OA). Then, to optimize the TMX loaded POE-40-S (P) surface-modified NLCs (TMX-loaded-PEG-40-S coated NLC (PNLCs) or PNLCs) by central composite design (CCD) using a four-factor, five-level model. The most influential factors affecting the PS was screened and optimized. The in-vitro study showed that increased drug-loading (DL) and encapsulation efficiency (EE), decreased PS and charge, sustained drug release for the prolonged period of the time with good stability and suppressed protein adsorption. The Ex-vivo study showed that decreased mucous binding with five-fold enhanced permeability of PNLC formulation after surface modification with POE-40-S. The in-vitro cytotoxicity study showed that the blank carrier is biocompatible and cytotoxicity of the formulation was dependent on the concentration of the drug. Finally, it can be concluded that the surface-modified PNLCs formulation was an effective, biocompatible, stable formulation in the enhancement of dissolution rate, solubility, stability with reduced mucus adhesion and increased permeability thereby which indicates its enhanced oral bioavailability.

Improved chemotherapeutic efficacy against resistant human breast cancer cells with co-delivery of Docetaxel and Thymoquinone by Chitosan grafted lipid nanocapsules: Formulation optimization, in vitro and in vivo studies. Colloids Surf B Biointerfaces 2019; 186:110603.

Abstract
In recent years, multi-targeted chemotherapeutic combinations have received considerable attention in solid tumor chemotherapy. Here, we optimized low-molecular-weight chitosan (CS)-grafted lipid nanocapsules (LNCs, referred to as CLNCs) for the co-delivery of docetaxel (DTX) and thymoquinone (THQ) to treat drug-resistant breast cancer. We first screened size reduction techniques (homogenization vs ultrasonication), and then the 33-Box-Behnken design was employed to determine optimal conditions of the final LNCs with the desired quality attributes. Uncoated LNCs had a particle size of 141.7 ± 2.8 nm (Polydispersity index, PdI: 0.17 ± 0.02) with entrapment efficiency (%EE) of 66.1 ± 3.5 % and 85.3 ± 3.1 % for DTX and THQ, respectively. The CS functionalization of LNCs improved the uptake and endosomal escape effect, and led to a significantly higher cytotoxicity against MCF-7 and triple-negative (MDA-MB-231) breast cancer cells. Furthermore, an enhanced antiangiogenic effect was observed with DTX- and THQ-carrying CLNCs in the Chick embryo chorioallantoic membrane (CAM) assay.

Abstract
Background:Genistein (Gen) is a naturally occurring soy isoflavonoid, possessing anticancer, antiproliferation & antioxidant-like properties. The disadvantage of poor solubility and less oral bioavailability restrict its use as a potential anticancer agent.Objectives:The current work was focused on the formulation and characterization of the genistein loaded nanostructured lipid carriers that can entrap enough quantity of the drug which will provide sustained release of the drug for the treatment of ovarian cancer.Methods:The nanostructure lipid carriers of genistein were developed with the aid of solvent emulsification and evaporation technique by employing TPGS as a surfactant. The resultant formulation was characterized by various physicochemical properties. Pharmacokinetics and biodistribution studies were carried out to estimate the mean plasma concentrations of the drug. Percentage cytotoxicity was evaluated by using PA-1 ovarian cancer cell lines.Results:The resultant formulation exhibited a particle size of 130.23 nm, and entrapment efficiency of 94.27 %, & zeta potential of -20.21 mV with unimodal size distribution. Pharmacokinetics and biodistribution studies revealed that the formulation was able to provide sufficient plasma drug concentration for the longer period of time and the drug was more distributed in ovarian cancer tissues. Results of MTT assay concluded that GenNLC were more effective in comparison to pristine Gen.Conclusion:In a nutshell, GenNLC seems to be a superior alternative carrier system for the formulation industry to obtain the higher entrapment with excellent stability of the formulation.

Abstract
Imatinib mesylate has been evaluated for possible potential in treatment of colon cancer in recent times. However, due to significant reporting of P-gp expression in colon cancer, it can come across set back due to MDR. Therefore, in present work the liposomal formulation containing imatinib-bile salt conjugate was developed and investigated for its comparative performance in MDR colon cancer cells and surface modified with hyaluronic acid for achieving low hemotoxicity with stealth characteristics. Imatinib was successfully conjugated with sodium-deoxycholate by charged conjugation and evaluated through FTIR, DSC and PXRD. The developed conjugate (IM-SD) was encapsulated in liposomes and the conditions were optimized by Box-Behnken statistical design to achieve a size of 56.56±1.23 nm along with 99.11±0.89% entrapment efficiency (LIPO). The liposomes were surface modified with hyaluronic acid and the size was enhanced to 159.14±3.2 nm (HA-LIPO). Flow cytometric studies demonstrated the enhanced uptake of P-gp substrate rhodamine dye in P-gp positive colo 320 colon cancer cells. In addition, an enhanced cellular internalization of HA-LIPO in CD-44 positive HT-29 and colo 320 cells indicates the targeting attributes of the hyaluronan coated liposomes. Finally, the hyaluronan coated liposomes were also found to have low opsonization activity.

Abstract
Over expression of P-glycoprotein (P-gp) in cancer cells often results in highly aggressive, multi-drug resistant (MDR) phenotype. Such tumors are very difficult to treat with conventional therapy and often lead to failure of the treatment. In this work, we fabricated surface engineered hybrid lipid nanoparticles grafted with novel AL-HA polymer by mineralization technique. AL-HA graft polymer was prepared by covalent conjugation of alendronate sodium and hyaluronic acid. Compritol ATO 888 and capmule MCM C8 hybrid lipid mix was employed to prepare irinotecan containing nanostructured lipid carrier (NLC) by using functional excipients with P-gp inhibition activity. AL-HA was successfully grafted over NLC-Ir (uncoated irinotecan loaded NLC) by calcium-assisted mineralization. HA-NLC-Ir (hyaluronic acid coated irinotecan loaded NLC) particles have a nanoscale size of 386±2.2 nm along with a zeta potential value of 19.7±1.2 mV. NLC-Ir as well as HA-NLC-Ir showed a slow and sustained drug release. In vitro cell line studies performed on HT-29 and Colo-320 colon cancer cells revealed a reduced IC50 even in MDR cells. Flowcytometry studies demonstrated the capability of the developed nanocarriers to deliver the P-gp substrate moieties in MDR cancer cells. Furthermore, the targeting potential of HA-NLC was confirmed by CLSM studies. The cell line studies also revealed that NLC formulation had a potential of inhibiting P-gp by affecting ATPase activity and MDR1 gene expression.

Abstract
We report crosslinker free self assembly of bovine serum albumin (BSA) and a hydrophobic payload paclitaxel (PTX), into nanoparticles by harnessing the temperature driven unfolding of protein. To systematically study the effects of various factors responsible for the key attributes of the nanoparticles, a Resolution IV design was used. 20 formulations were made with pH, temperature, time of heating before and after addition of drug, stirring rate, protein concentration, and protein to drug ratio selected as independent variables. Particle size, encapsulation efficiency, yield and zeta potential were the response variables. Perturbation and Pareto charts were used to single out the important factors, while, mathematical equations and 3D surface charts have been used to describe the relationship between dependent and independent variables. Nanoparticles with size of 188-482 nm were observed with a highly negative zeta potential of -39.5 to -21.9. Nanoparticles obtained had decent encapsulation efficiency (72.5-87.9%) with effective yield (80.0-93.8%). Validation of the mathematical models with 4 runs indicated the good prognostic ability of Resolution IV design. Spectroscopic studies suggested the non-covalent complexation between BSA and PTX as the possible mechanism of self assembly due to irreversible conformational changes in protein. Transmission Electron Microscopy (TEM) revealed spherical nanoparticles with a porous network of PTX-BSA. X-ray Diffraction (XRD) showed amorphous nature of nanoparticles. PTX release from the nanoparticles was found to be controlled release and followed Peppas-Sahlin model. In vitro cytotoxicity of PTX-BSA nanoparticles was comparable to that of Taxol after 48 h treatment. These findings suggest heat driven BSA self assembly as a viable approach to formulate cytotoxic drug carrying nanoparticles which could be efficiently used in anti-cancer therapy.

Abstract
A receptor level interaction of etoposide with P-glycoprotein (P-gp) and subsequent intestinal efflux has an adverse effect on its oral absorption. The present work is aimed to enhance the bioavailability of etoposide by co-administering it with quercetin (a P-gp inhibitor) in dual-loaded polymeric nanoparticle formulation. Poly-lactic-co-glycolic acid (PLGA) nanoparticles were optimized for various parameters like o/w phase volume ratio, poly-vinyl alcohol concentration, PLGA concentration and sonication time. The cytotoxicity studies (MTT assay) revealed a 9- and 11-fold decrease in the IC 50 values for etoposide-loaded nanoparticles (ENP) and etoposide + quercetin dual-loaded nanoparticles (EQNP) when compared to that of free etoposide, respectively, and the results were further supported by florescent-activated cell sorter studies. The confocal imaging of the intestinal sections treated with ENP and EQNP containing fluorescent probe (rhodamine) showed the superiority of the EQNP to permeate deeper. Furthermore, pharmacokinetic studies on rats revealed that EQNP exhibited a 2.4-fold increase in bioavailability of etoposide than ENP with no quercetin. The developed loaded nanoparticles have the high potential to enhance the bioavailability of the etoposide and sensitize the resistant cells.

Abstract
Raloxifene HCl (RLX), a selective oestrogen receptor modulator, has low oral bioavailability (<2%) in humans due to its poor aqueous solubility and extensive first-pass metabolism in gut. In this study, we optimised the method of preparation for poly (ε-caprolactone) (PCL) based nanocapsules of RLX by double emulsion method (w/o/w). A hybrid design approach, Plackett-Burman design followed by rotatable central composite design, was used to arrive at the optimised formulation. The optimised formulation was subjected to in vitro and in vivo evaluation. RLX loaded nanocapsules were spherical in shape with particle size less than 200 nm and high encapsulation efficiency (>80%). RLX-loaded nanocapsules showed 2.1-fold increase in oral bioavailability compared to free RLX. IV pharmacokinetic studies indicated that RLX loaded into nanocapsule had significantly low clearance in comparison with free RLX. Designed nanocapsules showed promise as delivery systems to enhance oral bioavailability and in reducing clearance of raloxifene.

Abstract
Triptolide (TP) often causes adverse reactions in the gastrointestinal tract when it is administered orally. This study aimed to prepare and optimize triptolide-loaded solid lipid nanoparticles (TP-SLN) with reduced gastric irritation. The microemulsion technique was used to formulate TP-SLN employing a five-level central composite design (CCD) that was developed for exploring the optimum levels of three independent variables on particle size, encapsulation efficiency (EE) and drug loading (DL). Quadratic polynomial models were generated to predict and evaluate the three independent variables with respect to the three responses. The optimized TP-SLN was predicted to comprise fraction of lipid of 49.73%, surfactant to co-surfactant ratio of 3.25, and lipid to drug ratio of 55.27, which showed particle size of 179.8 ± 5.7 nm, EE of 56.5 ± 0.18% and DL of 1.02 ± 0.003% that were in good agreement with predicted values. In addition, the optimized nanoparticles manifested a sustained-release pattern in vitro and were stable during 3 h of incubation in simulated gastric fluids without significant size change and the majority (91%) of the drug was protected. Furthermore, the nanoparticles did not show obvious gastric irritation caused by oral administration of TP in rats.
