Peptide Synthesis:

Peptides can be obtained chemically either by Solution-phase synthesis, or Solid-phase synthesis (SPPS), or even by a combination of both methods which, can involve various ligation strategies.

At ISSAR PHARMA, the synthesis of peptides is carried out on solid phase synthesis(solid support: Polystyrene, crosslinked with 1% divinylbenzene). Over the years, this method has shown a shift within the peptide synthesis community, and has now become the standard method for synthesising peptides and proteins.

General scheme of solid phase peptide synthesis: C to N direction. Synthesis cycle consists of De-protection, Washing’s, Coupling and Washings to remove excessive material.

Custom Peptide Synthesis:

ISSAR peptide production has a substantial, long –standing expertise in custom peptide synthesis services, peptides like, Bivalrudin, Oxytocin, Atosiban and Leuprolide etc….. We are sufficiently equipped to provide custom peptides with highest quality for complex or rare peptide sequences.

ISSAR developed a well researched knowledge to optimise the appropriate peptide synthesis method for each peptide.

State of the art Equipment


Issar’s purification department is well equipped with fully automated state of the art facility that is capable of purifying peptides from milligram to grams. The purification facility can be scalable from simple pilot systems to production scale levels.

The purification department is equipped for developing scale-up studies and optimising the peptides purification from mg scale to gram scale. For gram scale development and process optimisation a pilot system with collapsed columns of different sizes are available. The pilot system is equipped for linear and volumetric scale purification development and is equipped with gradient as well isocratic pumps which can be simulated with the production level purification systems and columns with required pressure and flow rate.

For manufacturing scale purification of peptides at Issar we have two Hanbon instruments equipped with a DAC columns, one column with dimensions size 150 x 650 mm and another with dimensions size 200 x 650 mm. The individual Hanbon instrument flow rates are 100ml to 1000 ml per minutes (150mm DAC) and 200ml to 2000ml per minute for 200mm DAC instrument. Both these columns are suitable to scale in manufacturing of peptides from a gram to kg.

Post purification supporting systems like Rotavapour (Buchi) and also Lyophilizers for concentration and Lyophiliztion of the desired peptides to scale from gram to kg is available. Department is also equipped with Shimadzu HPLC system for analysing online samples other than the complete analysis at QC.


Globally the first synthetic peptide based topical product in burn wound care. Completed all three phases of clinical development in India and submitted a dossier to Indian Regulatory for marketing approval. In the Phase III Clinical trial, apart from controlling infection, fastened wound healing, the product improved quality of life in burn wound patients, by reducing Post-Burn effects.

The Phase III Trial data has been presented at 17th Congress of the International Society for Burn Injuries (ISBI) Pre-Congress Work Shop on 14th October 2014, Sydney, Australia.

Product Name Xylentra™
Dosage Form Topical
Result Triple Action – Controls infection, accelerates wound healing & prevents scars.
Patent Patented
Expected Launch 2017

 What are burn wounds?


The Issar pharmaceuticals developed a synthetic peptide having anti-inflammatory properties studied initially by using IL-10 knock-out Murine colitis Model and later confirmed by DSS induced rat model which was evaluated by DAI, Histopathology and Biochemical markers. After reviewing the efficacy results the proof of concept studies and toxicological studies are planned.

 What is a Solid Tumor?


Issar pharmaceuticals developed a synthetic peptide for psoriasis which has remarkable potential in efficaciously attenuating the symptoms and processes underlying psoriasis-like dermatitis in mice. Being a lytic synthetic peptide having anti-angiolytic activity and anti inflammatory properties that could antagonize the deleterious effects of the pro inflammatory mediators responsible for the onset of the chronic disease, they may therefore prove to have potential in preventing, delaying and curing the disease and can open the way to new therapeutic strategies for psoriasis treatment.

However, though IMQ-induced dermatitis in mice may share the cytokine profile and histopathological findings to those of the psoriatic lesions in humans, further research is required to validate that they are the corresponding disease expressions. The current findings on the psoriasis-like mice model could be found appropriate on the human psoriatic model only after such validations and further clinical researches.

The peptide has completed Mechanistic profiling and shown good safety profile completed acute safety studies in rodents. Safety pharmacology and long term safety studies are proposed.

The peptide has been applied for patent protection. US IND filing is planned.

The peptide has shown efficacy in multiple animal models. It inhibited various cytokines (in vitro & Invivo), that are implicated in Psoriasis pathogenesis. The peptide is non-mutagenic, non-hemolytic. Non-GLP toxicity studies showed very good safety profile. GLP Toxicology programme is proposed.
Mechanistic studies have been completed.
The peptide has been applied for patent protection. US IND filing is planned.

Diabetic foot ulcer

ISSAR Synthethic Peptide represents a giant step forward in the treatment of chronic Diabetic foot ulcer,many concerns about the management of diabetic foot ulcers with Synthethic Peptide remain to be answered. In the future, it appears hopeful that a new generation of therapy will follow Synthethic Peptide for the treatment these chronic wounds.

What is Diabetic foot ulcer?

Diabetic foot ulcer is a major complication of diabetes mellitus, and probably the major component of the diabetic foot. It occurs in 15% of people with diabetes and precedes 84% of all diabetes-related lower-leg amputations. Diabetic neuropathic foot ulcers represent a serious health care burden to patients and to society. While the management of chronic diabetic foot ulcers has improved in recent years, it remains a frustrating problem for a variety of clinicians. Diabetes mellitus leads to a host of serious complications in multiple organ systems. Eventually, 15%–25% of all people with diabetes will develop a foot ulcer at some point in their lifetime. The management of foot ulcers and their associated morbidities is a leading cause of hospitalizations, and the occurrence of a foot ulcer significantly increases the risk of an amputation in diabetic patients. In fact, approximately 85% of all amputations for diabetic limbs were preceded by ulcers, culminating in 60,000–80,000 amputations performed yearly secondary to the failure of such wounds to heal. Indeed, most lower extremity amputations are performed in diabetic patients. The risk of death for a diabetic person who ends up with a below-knee amputation is 50% over 5 years. Much of this increased risk is attributable to the increased work of ambulating with a prosthetic limb and the resulting myocardial strain in these patients, most of whom have cardiovascular disease (Centers for Disease Control and Prevention 2005; Cowie et al 2006).
